[PATCH] nvme/tcp: release socket on sock_alloc_file() failure

[Wilfred Mallawa]

From: Wilfred Mallawa <wilfred.mallawa at wdc.com>

If sock_alloc_file() fails after a sock_create_kern() in
nvme_tcp_alloc_queue(), the socket is not released.

Add sock_release() to release the socket if sock_alloc_file() fails.

Fixes: e40d4eb84089eae1 ("nvme-tcp: allocate socket file")
