Peter Zijlstra 71fdb70eb4 sched/clock: Fix clear_sched_clock_stable() preempt wobbly ...

Paul reported a problems with clear_sched_clock_stable(). Since we run
all of __clear_sched_clock_stable() from workqueue context, there's a
preempt problem.

Solve it by only running the static_key_disable() from workqueue.
