Boqun Feng 857811a371 locking/ww_mutex: Adjust the lock number for stress test 
Because there are only 12 bits in held_lock::references, so we only

for ww_mutex stress test to kill one lockdep splat:

  [ ] [ BUG: bad unlock balance detected! ]

  [ ] ww_mutex_unlock()
  [ ] but there are no more locks to release!
