AP: Handle AP initalization failure in async flow

Browse Source 
When AP initialization is completed in a callback (e.g., OBSS scan),
wpa_supplicant_deinit_ap() is not called in case of failure. Fix this by
calling setup_complete_cb in case of failure, too, which in turn calls
wpa_supplicant_deinit_ap() if needed.
