Vincent Guittot d71744b5c1 sched/fair: Fix O(nr_cgroups) in the load balancing path 
commit 039ae8bcf7 upstream.

This re-applies the commit reverted here:

  commit c40f7d74c7 ("sched/fair: Fix infinite loop in update_blocked_averages() by reverting a9e7f6544b9c")

I.e. now that cfs_rq can be safely removed/added in the list, we can re-apply:

 commit a9e7f6544b ("sched/fair: Fix O(nr_cgroups) in load balance path")
