Rafael J. Wysocki cc8ea9dd0c sched: idle: Avoid retaining the tick when it has been stopped ...

commit 7059b36636 upstream.

If the tick has been stopped already, but the governor has not asked to
stop it (which it can do sometimes), the idle loop should invoke
tick_nohz_idle_stop_tick(), to let tick_nohz_stop_tick() take care
of this case properly.

Fixes: 554c8aa8ec (sched: idle: Select idle state before stopping the tick)
