Subject: [PATCH] compositor: make sync_updates_frozen no-op for unmanaged
 windows

Right now meta_compositor_sync_updates_frozen will crash if it's called
on a window that's not yet managed.

For future convenience, make it be a no-op instead, in the same way:

meta_compositor_window_shape_changed
and
meta_compositor_window_opacity_changed

are no-ops for unmanaged windows.
