+kernfs_deactivate() forgot to check whether KERNFS_LOCKDEP is set
+before performing lockdep annotations and ends up feeding
+uninitialized lockdep_map to lockdep triggering warning like the
+following on USB stick hotunplug.
+
+ usb 1-2: USB disconnect, device number 2
+ INFO: trying to register non-static key.
+ the code is fine but needs lockdep annotation.

+Fix it by making kernfs_deactivate() perform lockdep annotations only
