[PATCH v5 7/8] sched/numa: fix record hinting faults check

[Wanpeng Li]

Adjust numa_scan_period in task_numa_placement, depending on how much useful
work the numa code can do. The local faults and remote faults should be used
to check if there is record hinting faults instead of local faults and shared
faults. This patch fix it.
