After we landed bug 1072645, touch re-sampling may be broken. ex. Scrolling on Homescreen is not correct, and you cannot select any option in Settings. This bug also has impact on Project Silk.

Please turn on the preferences, gfx.frameuniformity.hw-vsync and gfx.touch.resample, and you can reproduce the problem. Jerry recorded the video for this bug, please check the attachment.

Accidentally removed too much code. I think clearing the move queue here is wrong - should be done on the input thread instead. But, this fixes things for now. Should probably also look for coalesced touch ups, but the old code had the same issue.
