sched/core: Simplify update_rq_clock() in __schedule()
Instead of relying on deactivate_task() to call update_rq_clock() and
handling the case where it didn't happen (task_on_rq_queued),
unconditionally do update_rq_clock() and skip any further updates.
This also avoids a double update on deactivate_task() + ttwu_local().
