sched/fair: Cleanup pick_task_fair() vs throttle
Per 54d27365cae8 ("sched/fair: Prevent throttling in early
pick_next_task_fair()") the reason check_cfs_rq_runtime() is under the
'if (curr)' check is to ensure the (downward) traversal does not
result in an empty cfs_rq.
But then the pick_task_fair() 'copy' of all this made it restart the
traversal anyway, so that seems to solve the issue too.
