surface-actor: Add NULL check for stage

Browse Source 
In some cases Wayland surface actors are not decendents of the stage,
notably subsurfaces without a parent surface. The code changes in the
mentioned commits dropped the previously existing check for that - readd
it.

Fixes: 627ab24721 (surface-actor: Add meta_surface_actor_schedule_update())
Fixes: 7eb99ddef7 (wayland/surface: Schedule updates in the context of the surface actor)
