Cycles: Removed scaling from Embree's object motion blur.

Cycles native drops scaling from motion interpolation, the scale of the center of the frame gets reused to all motion positions. Embree could interpolate scaling too, but mixing the two then causes trouble with secondary rays, as Cycles does its own transformation interpolation in the intersection refinement. For now, restrict Embree to the common denominator, hopefully soon we can reintroduce scaling motion blur to Cycles.
