qcacld-3.0: Use Reassociation during BSS Transition
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.
