This has nothing to do here (freeing is not unlinking/remapping!), and was actually redoing something already taken care of by `BKE_libblock_relink_ex()` call in `BKE_libblock_free_ex()`. Also, gives some noticeable speedup when removing datablocks with do_unlink=True, about 5 to 10% quicker e.g. when deleting all objects from a py console, in a big production file...
