spans-compositor: Only destroy the clip if we made the copy

Browse source 
The extents->clip may be replaced elsewhere and so we cannot assume that
simply because it changed from the stashed value, that it was us that
made that copy. So becareful to only free our copy.

Fixes a double-free of a clip after a complex fallback operation.
