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.
