slub: tidy up initialization ordering
- free_kmem_cache_nodes() frees the cache node before nulling out a reference to it - init_kmem_cache_nodes() publishes the cache node before initializing it Neither of these matter at runtime because the cache nodes cannot be looked up by any other thread. But it's neater and more consistent to reorder these.
