P2P: Do not accept any GO BSS entry if SSID is specified for join

Browse source 
Accept only a BSS entry matching the SSID when trying to find the
operating channel of a GO during join operation for which the SSID was
already specified. Previously, it could have been possible to pick an
incorrect BSS entry if the new GO was not found in the latest scan and
there was an older cached scan entry for the same BSSID.
