sched: New helper to prevent from stopping the tick in full dynticks
Provide a new helper to be called from the full dynticks engine
before stopping the tick in order to make sure we don't stop
it when there is more than one task running on the CPU.
This way we make sure that the tick stays alive to maintain
fairness.
