slub: Fix kmem_cache_destroy() with SLAB_DESTROY_BY_RCU
kmem_cache_destroy() should call rcu_barrier() *after* kmem_cache_close() and *before* sysfs_slab_remove() or risk rcu_free_slab() being called after kmem_cache is deleted (kfreed). rmmod nf_conntrack can crash the machine because it has to kmem_cache_destroy() a SLAB_DESTROY_BY_RCU enabled cache.
