slab: partially revert list3 changes
Partial revert the changes made by 04231b3002ac53f8a64a7bd142fde3fa4b6808c6
to the kmem_list3 management. On a machine with a memoryless node, this
BUG_ON was triggering
static void *____cache_alloc_node(struct kmem_cache *cachep, gfp_t flags, int nodeid)
{
struct list_head *entry;
struct slab *slabp;
struct kmem_list3 *l3;
void *obj;
int x;
l3 = cachep->nodelists[nodeid];
BUG_ON(!l3);
