Only try fast reconnect if network is not disabled

Browse source 
Previously, it would have been possible for the network to be marked
disabled and that marking to be ignored if a recoverable disconnection
reason event were processed. Avoid this by verifying network status
before trying to reconenct back to the same BSS.
