wayland: Check surface before looking up modals

Browse Source 
Near window destruction, there might be cases where the surface
actor does no longer have a surface, yet it's still in the stage
and eligible for picking. In that situation looking for modal
dialogs attached to this surface will evidently fail, so avoid
this check on a NULL surface.
