wpa_supplicant: Set state to DISCONNECTED on AP creation errors

If the AP creation failed (missing freq= or driver error) the supplicant
would previously stay in SCANNING state forever. Instead, it should
handle the error a bit better and drop back to DISCONNECTED so clients
know something went wrong.
