station: Make sure bss_match also matches the ssid 

Kernel might report hidden BSSes that are reported from beacon frames
separately than ones reported due to probe responses.  This may confuse
the station network collation logic since the scan_bss generated by the
probe response might be removed erroneously when processing the scan_bss
that was generated due to a beacon.

Make sure that bss_match also takes the SSID into account and only
matches scan_bss structures that have the same BSSID and SSID contents.
