 - Fix handling of throttled parents in enqueue_task_fair() completely. The
   recent fix overlooked a corner case where the first iteration terminates
   do a entiry being on rq which makes the list management incomplete and
   later triggers the assertion which checks for completeness.

 - Fix a similar problem in unthrottle_cfs_rq().

 - Show the correct uclamp values in procfs which prints the effective
   value twice instead of requested and effective.
