[PATCH] Interworking: don't filter probe requests when interworking is disabled.

[Maxime Bizon]

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 to match the
behaviour of code without CONFIG_INTERWORKING
