vhost: add missing __user annotations
Several vhost functions were missing __user annotations on pointers, causing sparse warnings. Fix this up. sparse also warns about vhost_process_iotlb_msg which is local and should be static. Fix that up as well. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
