clutter/stage-cogl: Cleanup setting of the damage history

Browse Source 
Since we now check for the buffer age before setting up the
fb_clip_region, that region will be set to the full extents of the view
in case the buffer age is invalid. This in turn means we don't have to
do this again later and can simply fill the damage history with the
fb_clip_region that's already set for us.
