SLUB: Use ->objsize from struct kmem_cache_cpu in slab_free()
There's no reason to use ->objsize from struct kmem_cache in slab_free() for the SLAB_DEBUG_OBJECTS case. All it does is generate extra cache pressure as we try very hard not to touch struct kmem_cache in the fast-path. Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>
