dix: drop x/y back into last.valuators before updating the history (#19285) 

positionSprite needs to scale to screen coordinates and in the process of
doing so alters dev->last.valuators[0:1]. Drop the real coordinates back after
finishing and before updating the motion history. This way, we don't push the
screen coordinates into the motion history.
