Interworking: Don't filter probe requests when interworking is disabled

Browse source 
With hidden SSID (ignore_broadcast_ssid), an IOS device trying to
connect to the AP will send a probe request with ANT == 2. If
interworking support is just compiled (not enabled), we will drop the
probe request since default ANT is 0.

Check that interworking is enabled before filtering based on ANT or
HESSID to match the behavior of code without CONFIG_INTERWORKING.
