scsi: qla2xxx: Only allow operational MBX to proceed during RESET.
This patch is allowing only ROM mailbox command which are necessary to initialize chip after a reset has been issued. In a target environment, there could be a user space daemon which can issue statistics and other management mailbox command which are non-critical. This patch will timeout non critical mailbox commands immediately rather than waiting for timeout, if driver detects that chip reset has been issued or chip reset is in progress.
