SAE: Send external auth failure status to driver

Browse Source 
wpa_supplicant prepares auth commit request as part of the external
authentication (first SAE authentication frame), but it fails to get
prepared when wpa_supplicant is started without mentioning the SAE
password in configuration. Send this failure status to the driver to
make it aware that the external authentication has been aborted by
wpa_supplicant.
