Waiman Long 1d61659ced locking/rwsem: Disable preemption in all down_write*() and up_write() code paths 
The previous patch has disabled preemption in all the down_read() and
up_read() code paths. For symmetry, this patch extends commit:

  48dfb5d2560d ("locking/rwsem: Disable preemption while trying for rwsem lock")

... to have preemption disabled in all the down_write() and up_write()
code paths, including downgrade_write().
