scsi: qla2xxx: Prevent command send on chip reset

Browse source

Currently IOCBs are allowed to push through while chip reset could be in
progress. During chip reset the outstanding_cmds array is cleared
twice. Once when any command on this array is returned as failed and
secondly when the array is initialize to zero. If a command is inserted on
to the array between these intervals, then the command will be lost.  Check
for chip reset before sending IOCB.
