Fix T97908: Cycles missing motion from on pointcloud generated by geometry nodes

Assume geometry is always potentially animated, since we can't use our heuristic
to detect if the object is potentially animated by looking at modifiers on the
object.

The main original reason for this check was to avoid evaluating subdivision
surfaces for many static objects, which is not happening here anyway.
