damage: untwist Xinerma handling 

The diffenciation between Xinerama and single screen version is by tweaking
call vectors unncessarily complicated: it the only reason why these are
needed in the first place. Finally, it's just about one function, so it's
much easier just branching off in ProcDamageCreate() in case of Xinerama
is enabled.

This also clears the road for further simplification of the dispatcher.
