mm/sl[aou]b: Get rid of __kmem_cache_destroy
What is done there can be done in __kmem_cache_shutdown. This affects RCU handling somewhat. On rcu free all slab allocators do not refer to other management structures than the kmem_cache structure. Therefore these other structures can be freed before the rcu deferred free to the page allocator occurs.
