It's possible from wpa_s to change the state from completed to scanning
without going through disconnected state if interface signals that the carrier
went off and on (IFF_LOWER_UP flag).
This will cause dead lock similar in c810464828d6764bea304de3e9b6b151aa05e313
if the wifi gets into associating state as the network->connected is still true
but wifi->connected is not.
