sched: clean up fixup_hmp_sched_stats()
The commit 392edf4969d20 ("sched: avoid stale cumulative_runnable_avg
HMP statistics) introduced the callback function fixup_hmp_sched_stats()
so update_history() can avoid decrement and increment pair of HMP stat.
However the commit also made fixup function to do obscure p->ravg.demand
update which isn't the cleanest way.
Revise the function fixup_hmp_sched_stats() so the caller can update
p->ravg.demand directly.
