present: fix bad logic in cancelling scheduled operations.

Browse Source 
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
e6f5d9d7b7

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