[PATCH] present: Remove executing vblank from window list. Bug# 79709.

[Keith Packard]

Once the vblank is actually getting executed, it's lifetime is no
longer tied to the window, and so it shouldn't be controlled by window
destruction. In particular, if the vblank is queued for flip, it will
get stored in the flip_pending field, and will be correctly destroyed
when the flip completes.
