slab: fix bootstrap on memoryless node
If the node we're booting on doesn't have memory, bootstrapping kmalloc() caches resorts to fallback_alloc() which requires ->nodelists set for all nodes. Fix that by calling set_up_list3s() for CACHE_CACHE in kmem_cache_init(). As kmem_getpages() is called with GFP_THISNODE set, this used to work before because of breakage in 2.6.22 and before with GFP_THISNODE returning pages from the wrong node if a node had no memory. So it may have worked accidentally and in an unsafe manner because the pages would have been associated with the wrong node which could trigger bug ons and locking troubles.
