For write_pending if the queue is down or client failed
then return -EIO so that LIO can properly process the
completed command. Prior we returned 0 since LIO could
not handle it properly. Now with:
target: Fix unknown fabric callback queue-full errors
that patch addresses LIO's ability to handle things right.

Thanks! I forgot to add the stable tag for 4.11+, but I guess we can 
wait for
Nick to reply since we had discussed making the dependent patch series 
stable.
