qcacld-3.0: Fix to avoid checking PCL when BSSID is given by upper layer

New flavor of OS is sending bssid along with STA connect command. When
connect command comes with bssids then don't allow Preferred channel
list algorithm as it won't be of any use and skipping the algorithm will
improve initial scan time.

Add log to inform whether BSSID hint is given by upper layer.
