[PATCH] present: fix bad logic in cancelling scheduled operations.

[Axel Davy]

If we present several pixmaps in advance for different msc, the later one
shouldn't cancel the previous ones.

This reverts a change made by commit
e6f5d9d7b7efdacea0f22f1808efca849bcede4c

Without this fix, vblank_mode=0 glxgears doesn't update
with the present fallback.
