[PATCH 1/2] Always call the flush callback chain when we might send out damage events

We were missing the callback in a couple of places.  Drivers may use
the flush callback to submit batched up rendering before events (for
example, damage events) are sent out, to ensure that the rendering
has happend when the client receives the event.
