qcacld-3.0: Invoke LFR3 roaming on reception of prev_bssid in connect

Browse source 
When supplicant issues connect with prev_bssid set, it expects the
driver to do reassociation instead of disconnect and connect.

This fix checks if prev_bssid is set and bssid/bssid_hint, channel/
channel_hint parameters are present in connect and if yes, invokes LFR3
roaming.
