compositor: flush the batched up damage when shm buffer is destroyed

Since we now batch up damage and only handle it at repaint time, we need
to apply it in case a buffer is destroyed so we don't lose it.

Ander found the problem, but we need to fix it in the compositor so we
don't change the behavior of the compositor.
