drm/virtio: Disable damage clipping if FB changed since last page-flip

drm/virtio: Disable damage clipping if FB changed since last page-flip

commit 0240db231dfe5ee5b7a3a03cba96f0844b7a673d upstream.

The driver does per-buffer uploads and needs to force a full plane update
if the plane's attached framebuffer has change since the last page-flip.
