Subject: [PATCH] slub: sysfs_slab_remove should free kmem_cache when debug is enabled
kmem_cache_destroy use sysfs_slab_remove to release the kmem_cache,
but when CONFIG_SLUB_DEBUG is enabled, sysfs_slab_remove just release
related kobject, the whole kmem_cache is missed to release and cause
a memory leak.
