If the SIM freezes the queue at exactly the wrong moment, after
another thread has started to send in a CCB and already checked the queue wasn't frozen, we would end up with iscsi_action() being called despite the queue is now frozen. Add a check to make sure this doesn't happen . Perhaps this should be fixed at the CAM level instead, but given how the send queue and SIM are governed by two separate mutexes, it is somewhat hard to do.
