Michal Suchanek 88c767edb0 Fix crash for motion events from devices without valuators ...

A WarpPointer request may trigger a motion event on a device without
valuators. That request is ignored by GetPointerEvents but during smooth
scroll emulation we dereference dev->valuators to get the number of axes.

Break out early if the device doesn't have valuators.
