slab: fix cache_cache bootstrap in kmem_cache_init()
upstream commit: ec1f5eeeb5a79a0d48036de649a3498da42db565
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.
