Subject: [PATCH xserver 6/7] xwayland: Don't need xwl_window anymore in
 xwl_present_queue_vblank

Fixes issue #12. Presumably the problem was that Present operations on
unmapped windows were executed immediately instead of only when reaching
the target MSC.

(cherry picked from commit f541615342ce6bfb0e6d4e68deb3a924a87e8ba9)
