[PATCH] ephyr: Free damage structure at server reset time

The usual mechanism for freeing a damage structure when the pixmap is
destroyed does not work for the screen pixmap as it isn't freed in the
normal way.
The existing driver cleanup function, scrfini, is called after the
wrapped CloseScreen functions, including damageCloseScreen, are called
and thus ephyr can't free the damage structure at that point.
Deal with this by providing an early CloseScreen hook in KdCloseScreen
which ephyr can use to free the damage structure before damage itself
shuts down.
