sched/core: Unify p->on_rq updates

Browse source

Almost all {,de}activate_task() invocations pair with p->on_rq
updates, the exception being the usage in rt/deadline which hold both
rq locks and therefore don't strictly need to set
TASK_ON_RQ_MIGRATING, but it is harmless if we do anyway.

Put the updates in {,de}activate_task() and cut down on repetition.
