[RFC,v2 2/3] sched: set number of iterations to h_nr_running

[Uladzislau Rezki]

From: Uladzislau 2 Rezki <uladzislau2.rezki@xxxxxxxxxxxxxx>

It is possible that busiest run queue has multiple RT tasks,
whereas no CFS tasks, that is why it is reasonable to use
h_nr_running instead, because a load balance only applies
for CFS related tasks.
