slab: fix cache_cache bootstrap in kmem_cache_init()

Commit 556a169dab38b5100df6f4a45b655dddd3db94c1 ("slab: fix bootstrap on
memoryless node") introduced bootstrap-time cache_cache list3s for all nodes
but forgot that initkmem_list3 needs to be accessed by [somevalue + node]. This
patch fixes list_add() corruption in mm/slab.c seen on the ES7000.
