SLAB: Fix lockdep annotation breakage
Commit ce79ddc8e2376a9a93c7d42daf89bfcbb9187e62 ("SLAB: Fix lockdep annotations for CPU hotplug") broke init_node_lock_keys() off-slab logic which causes lockdep false positives. Fix that up by reverting the logic back to original while keeping CPU hotplug fixes intact.
