virtio_blk: fix panic in initialization error path
[ Upstream commit 6bf6b0aa3da84a3d9126919a94c49c0fb7ee2fb3 ]
If blk_mq_init_queue() returns an error, it gets assigned to
vblk->disk->queue. Then, when we call put_disk(), we end up calling
blk_put_queue() with the ERR_PTR, causing a bad dereference. Fix it by
only assigning to vblk->disk->queue on success.
