Remove unused P2P device discovery hack from Beacon configuration

AP mode operations were used for P2P device discovery Listen state
only during early experiments. This has now been cleaned up and
ieee802_11_set_beacon() is not called for P2P device discovery.
As such, this hack to skip Beacon configuration can be removed.
