description:
Uncomment call to genfs_rename_cache_purge.

Fixes a side issue mentioned in PR kern/46990.

I left this commented to preserve the old behaviour of tmpfs_rename,
but it is obviously broken to omit the cache purge, and I'm surprised
nobody had encountered any problems with it until now.
