hostapd: return with 80211 codes in handle event function

If the auth or assoc request was denied the reason
was always WLAN_STATUS_UNSPECIFIED_FAILURE.
That's why for example the wpa supplicant was always
trying to reconnect to the AP.
Now it's possible to give reasoncodes why the auth
or assoc was denied.
