Waiman Long f9e21aa9e6 locking/rwsem: No need to check for handoff bit if wait queue empty 
Since commit d257cc8cb8d5 ("locking/rwsem: Make handoff bit handling
more consistent"), the handoff bit is always cleared if the wait queue
becomes empty. There is no need to check for RWSEM_FLAG_HANDOFF when
the wait list is known to be empty.
