Would probably be cleaner as:

static struct virtio_blk_vq *get_virtio_blk_vq(struct blk_mq_hw_ctx *hctx)
{
	struct virtio_blk *vblk = hctx->queue->queuedata;

	return &vblk->vqs[hctx->queue_num];
}

dropping the 'vq' variable, and also dropping the inline as the compiler
will work that out anyway.

Apart from that minor nit, looks good to me.
