sched: window-stats: Do not account wait time
Task load statistics are used for two purposes : cpu frequency
management and placement. Task's load can't be accurately judged by
its wait time. For ex: a task could have waited for 10ms and when given
opportunity to run, could just execute for 1ms. Accounting for 11ms as
task's demand could be over-stating its needs in this example. For
now, remove wait time from task demand and instead let task load be
derived from its actual exec time. This may need to become a tunable
feature.
