The function __lim_process_sme_join_req dereferences the
sme_join_req pointer without checking even if msg_buf
is NULL. The function also returns if qdf_mem_malloc
fails for sme_join_req or mlm_join_req without giving any
join response.
Fix is to use lim_get_session_info function that checks
if msg_buf is NULL, and then assign the corersponding
value. The function __lim_process_sme_join_req also send
the join response with the failure reason.

This is qcacld-2.0 to qcacld-3.0 propagation
The BSS transition request is handled by the supplicant.
The supplicant upon receiving the request will issue a
connect request to the driver with a hint of prev_bssid
telling the driver to perform a re-association.
Use this hint in the driver and initiate a re-association.
While doing the re-association, there is no need to do a
scan if the target AP is already present in the scan cache.
Optimize the re-association code to not do a scan if not
necessary in this particular case.
