qcacld-3.0: Check for zero/broadcast BSSID in BLM

Browse Source 
Currently the BLM does not check the BSSID of
the entry for 0 or broadcast BSSID, and thus
can lead to addition of many entries with such
property.
This would also result in removal of old valid BSSID
entry data, which is essentially required.

Fix is to check the BSSID of the entry for 0
or broadcast, and reject them if not valid.
