Remove unused leftover from multi-SSID design

Browse Source 
The multi-SSID design that used a single beaconing BSSID with multiple
SSIDs was never completed in this repository, so there is no need to
maintain the per-STA ssid/ssid_probe pointers that could only point to
&hapd->conf->ssid. Save some memory and reduce code complexity by
removing this unused partial capability.
