Handle assoc reject events without wpa_supplicant SME

If the driver indicates the association (or authentication) was
rejected, wpa_supplicant should handle this connection failure similarly
to other cases. Previously, this was only handled with drivers that use
wpa_supplicant SME.

In case of cfg80211-based drivers, a rejected association was actually
already handled since cfg80211 generates a deauthentication event after
indicating connection failure. However, rejected authentication resulted
in wpa_supplicant waiting for authentication timeout to expire which is
unnecessary long wait.

Fix this by calling wpas_connection_failed() to use the common mechanism
to reschedule a new connection attempt with the previously attempted
BSSID blacklisted.
