Subject: [PATCH] sched: update aggregate when holding the RQs

It was observed that in __update_group_shares_cpu()

  rq_weight > aggregate()->rq_weight

This is caused by forks/wakeups in between the initial aggregate pass and
locking of the RQs for load balance. To avoid this situation partially re-do
the aggregation once we have the RQs locked (which avoids new tasks from
appearing).
