Fix T78666: Cycles non-uniformly scaled hair renders wrong for static objects

Don't apply the matrix transform optimization in this case, curve points and
radius can't represent non-uniform scale the way is possible with triangle
meshes and vertices.

This would cause abrupt change if objects had e.g. motion blur in one frame
and not in the next.
