qcacld-3.0: Handle fast reassoc with mac address set to zero

When fast reassoc command is received with bssid
and channel frequency set to zero, if no candidate
found, STA DUT should disconnect.
Currently STA DUT stays on the same AP.

Fix is to add bssid zero check and disconnect from
current AP.
