Since update_rq_runnable_avg is used only by cfs scheduler, it
should not consider the task beyond the cfs type.
If one cfs task is running with one rt task, the only cfs task
should be no aware of the existence of rt task, and behavior
like one cfs task occasionly throttled by some bandwidth control
mechanism. Thus its sleep time should not being taken into
runnable avg load calculation.
