Target_lock was a global lock for all target and copy engine data
structure access. Replacing target_lock with a per copy engine
lock permits paralel completion handling for different copy engines.

Currently in SAP mode, if max STA connected a operation to turn off
SAP will result in more than SME queue length cmds being enqueued.
To fix, this patch:
1) Makes the SME cmd queue length, 3 times the max STA.
2) Because of increased SME cmds, the allocation for all cmds
together will fail, hence allocate each SME cmd individually
and free them accordingly.

qcacld-2.0 to qcacld-3.0 propagation
Few STA/P2P-client's are sending assoc req frame and waiting for
300-500ms. If they don't receive the assoc resp frame within
this time then they resending the assoc req frame. These frames
are not going to have retry bit set.
In the current design host driver is not handling these duplicate
assoc req frames without retry bit set.
To mitigate this issue, while processing assoc request frame,
if pStaDs entry already exists then send assoc response with
same tid and stop processing the assoc req further.

qcacld-2.0 to qcacld-3.0 propagation
When disassoc request is received from peer and at the same time
if deauth request is received from supplicant, LIM cleanup
may not happen properly as there is a chance of session deletion
in limSendSmeDeauthNtf while cleanup in progress from
limProcessSmeDisassocCnf. This can result in not sending delbss to FW.
Hence, FW can crash when config bss is sent for new connection.
Following changes are added to handle this.
1. Add state eLIM_SME_WT_DISASSOC_STATE in __limProcessSmeDeauthReq
and allow host to post LIM_MLM_DEAUTH_REQ instead of invoking
limSendSmeDeauthNtf, where session is deleted.
2. Send eWNI_SME_DEAUTH_RSP if cleanup is already in progress to avoid
cleanup again. If mlm state is not eLIM_MLM_LINK_ESTABLISHED_STATE,
then it means cleanup is already in progress.
3. Return from __limProcessSmeDisassocCnf if cleanup is already in
progress.
4. Add check in limProcessMlmDeauthCnf to send deauth confirmation even
if state is eLIM_SME_WT_DISASSOC_STATE.
5. Add similar checks in limProcessMlmDisassocReqNtf to handle disassoc
from peer and supplicant simultaneously.

This is a qcacld-2.0 to qcacld-3.0 propagation.
The problem with the current code is we are finding whether connected or
pno_in_progress or extscan_in_progress in the same for loop and whenever
one of them matches, we break out of loop. It makes sense to keep
connected flag and pno_in_progress inside the for loop because both are
mutually exclusive. But same is not the case with extscan_in_progress,
this flag can be set to true or false irrespective of connected or
pno_in_progress.
Hence the fix is to move finding extscan_in_progress to a separate for loop.

This is a qcacld-2.0 to qcacld-3.0 propagation.
Currently WOW_NLO_SCAN_COMPLETE_EVENT is enabled on receiving
PNO match found event, but it is never cleared.
This is causing regular host wake ups with the reason
WOW_REASON_NLO_SCAN_COMPLETE even if pno match is not found in the
next successive iterations.
Fix this by enabling/disabling WOW_NLO_SCAN_COMPLETE_EVENT before suspend
based on the flag pno match is found.

This is a qcacld-2.0 to qcacld-3.0 propagation.
With RunTime PM feature enabled, after receiving the PNO matched event
RunTime PM puts the host back in WoW suspend after 500ms (default).
Since WMI_NLO_SCAN_COMPLETE_EVENTID is not a wakeable event, this event
does not wakeup the host hence PNO scan not completed and PNO is broken.
Fix this by making NLO_SCAN_COMPLETE_EVENT a wakeable event.
Host driver configures this WoW event only after PNO match is received.
