WNM: Ignore SSID check for hidden SSID in transition candidates

Do not skip scan results with zero length SSID (i.e., a hidden SSID)
when searching for potential BSS transition candidates since such
entries might be for the same ESS (i.e., for the current SSID). Use only
the BSSID check for such cases.
