vhost: missing __user tags
sparse warns about converting void * to void __user *. This is not new
but only got noticed now that vhost is built on more systems.
This is just a question of __user tags missing in a couple of places,
so fix it up.
Fixes: f88949138058 ("vhost: introduce O(1) vq metadata cache")
