Dirty change in union_lock().  Sometimes upper vnode is locked without
UN_ULOCK flag.  This shows a locking violation but I couldn't find the
reason UN_ULOCK is not set or upper vnode is not unlocked.  I added
the code that detect this case and adjust un_flags.  DIAGNOSTIC kernel
doesn't adjust un_flags, but just panic here to help debug by kernel
hackers.
