mm/slab.c: remove redundant assignments for slab_state
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.
