Subject: sched: Revert nohz_ratelimit() for now

commit 396e894d289d69bacf5acd983c97cd6e21a14c08 upstream.

Norbert reported that nohz_ratelimit() causes his laptop to burn about
4W (40%) extra. For now back out the change and see if we can adjust
the power management code to make better decisions.
