slab_state is being set to "UP" in create_kmalloc_caches(), and later on
we set it again in kmem_cache_init_late(), but slab_state does not change
in the meantime.
Remove the redundant assignment from kmem_cache_init_late().
And unless I overlooked anything, the same goes for "slab_state = FULL".
slab_state is set to "FULL" in kmem_cache_init_late(), but it is later being set
again in cpucache_init(), which gets called from do_initcall_level().
So remove the assignment from cpucache_init() as well.
