compositor-drm: Check surface's outputs when assigning overlays

Browse Source 
Check if the output passed to drm_output_prepare_overlay_surface() does
actually contain the surface and fail if it doesn't. Also fail if a
surface spans multiple outputs since clearing the damage will cause the
portion that is not in an overlay to not be updated at all.
