MetaSurfaceActorWayland: Unset the MetaWaylandSurface pointer when it goes away

Browse Source 
We may access it during painting even if it has been freed. For now,
manually unset it during the MetaWaylandSurface cleanup; in the future
make MetaWaylandSurface a GObject and make the surface pointer a weak
reference.
