sched: WALT: fix broken cumulative runnable average accounting

When running tasks's ravg.demand is changed update_history() adjusts
rq->cumulative_runnable_avg to reflect change of CPU load.  Currently
this fixup is broken by accumulating task's new demand without
subtracting the task's old demand.

Fix the fixup logic to subtract the task's old demand.
