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.
