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") Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
