Clear wpa_supplicant state to DISCONNECTED on FLUSH command

Browse source 
It was possible for the FLUSH command to trigger auto connect mechanism
to schedule a new scan in 100 ms. This is not desired since all the
network profiles will be removed immediately and the scan or an attempt
to reconnect would not be of any benefit here. Such a scan in 100 ms can
cause issues for cases where multiple test sequences are run back to
back, so prevent this by clearing wpa_supplicant state to DISCONNECTED
(which avoids scheduling of the 100 ms scan trigger on disconnection) if
the state was AUTHENTICATING or higher when the FLUSH command was
issued.
