P2P: Fix GO start on interface that has active station connection

The active station connection triggered wpa_supplicant AP mode startup
to try to update Beacon IEs before the AP mode was properly initialized
and that resulted in NULL pointer dereference in driver_nl80211.c. Fix
this by skipping the IE update before the AP mode is initialized.
