sched/fair: Always trigger resched at the end of a protected period
Always trigger a resched after a protected period even if the entity is still eligible. It can happen that an entity remains eligible at the end of the protected period but must let an entity with a shorter slice to run in order to keep its lag shorter than slice. This is particulalry true with run to parity which tries to maximize the lag.
