nbd: blk_mq_init_queue returns an error code on failure, not NULL


[ Upstream commit 25b4acfc7de0fc4da3bfea3a316f7282c6fbde81 ]

Additionally, don't assign directly to disk->queue, otherwise
blk_put_queue (called via put_disk) will choke (panic) on the errno
stored there.

Bug found by code inspection after Omar found a similar issue in
virtio_blk.  Compile-tested only.
