Peter Zijlstra 7c3edd2c30 sched/fair: Improve PELT stuff some more 
Vincent noted that the update_tg_load_avg() usage in commit:

  3d30544f02 ("sched/fair: Apply more PELT fixes")

isn't entirely sufficient. We need to call this function every time
cfs_rq->avg.load changes, this includes when update_cfs_rq_load_avg()
returns true, but {attach,detach}_entity_load_avg() themselves also
change it. This means we need to unconditionally call
update_tg_load_avg().

Also, add more comments.
