Depsgraph: Fix copy-on-write assert when freeing Freestyle config

We were bumping user count when duplicating viewlayer and its freestyleconfig
depending on the flag, however when freeing we were always decreasing user
count.

This fixes this and get rid of the assert when running:
`--factory-startup --enable-copy-on-write`

And closing Blender.
