[ Upstream commit 5572a55a6f830ee3f3a994b6b962a5c327d28cb3 ]
If the commands allocation fails in nvmet_tcp_alloc_cmds()
the kernel crashes in nvmet_tcp_release_queue_work() because of
a NULL pointer dereference.
nvmet: failed to install queue 0 cntlid 1 ret 6
Unable to handle kernel NULL pointer dereference at
virtual address 0000000000000008
Fix the bug by setting queue->nr_cmds to zero in case
nvmet_tcp_alloc_cmd() fails.
Fixes: 872d26a391da ("nvmet-tcp: add NVMe over TCP target driver")
