As a part of LL stats get NB operation, the driver sends the LL stats
req to the FW, waits for the response and sends back the stats in a
synchronous reply. All this happens as a part of one single NB
operation.
Within this operation, if an rmmod comes, there can be a possiblity
of a memory leak. In function hdd_link_layer_process_radio_stats, there
is a check to validate the hdd_context and return if the driver is
undergoing load/unload. As a part of the premature return, some stats
are not returned to user space..
To resolve this, remove the validity check from the NB operation. The
operation itself comes with DSC synchronization and ensures that the
hdd_context remains valid atleast until the operation is complete. Thus
there is no need for the redundant check of validity of hdd_context.

QCA_NL80211_VENDOR_SUBCMD_NAN_EXT is introduced to carry NAN
command data along with channel info. This channel info is needed
to enable DBS on DBS supported platforms. The command data is sent
to firmware as it on non-DBS platforms.
Userspace is expected to send NAN commands through
QCA_NL80211_VENDOR_SUBCMD_NAN_EXT if it's supported. It can send
QCA_NL80211_VENDOR_SUBCMD_NAN if QCA_NL80211_VENDOR_SUBCMD_NAN_EXT
is not supported, which is expected to happen on older
platforms(non-DBS).
So legacy NAN command QCA_NL80211_VENDOR_SUBCMD_NAN is not allowed
on DBS platforms, as the command is sent to firmware without
enabling DBS.
Event part of QCA_NL80211_VENDOR_SUBCMD_NAN is still intact as it
carries NAN events from firmware to userspace.

Kernel 5.4 has applied batched GRO_NORMAL packets processing
for all napi_gro_receive() users. this requires NAPI users to
call napi_complete_done() or napi_complete() at the end of every
polling to flush batched GRO_NORMAL packets.
However, by current wlan driver design, napi_gro_recevie()
is not happened in same NAPI polling context and done in another
thread context, it likely packets which have not been flushed from
napi->rx_list will get stall until next RX cycle.
Fix this by adding a manual flushing of the list right after
napi_gro_flush() call to mimic napi_complete() logics.
