Sagi Grimberg 22d908afbd nvmet-tcp: fix lockdep complaint on nvmet_tcp_wq flush during queue teardown 
[ Upstream commit 533d2e8b4d ]

We probably need nvmet_tcp_wq to have MEM_RECLAIM as we are
sending/receiving for the socket from works on this workqueue.
Also this eliminates lockdep complaints:
--
