Fix two stale function/callback name references in comments:
1. Remove a stale comment referencing sched_rt_avg_update(),
which was removed in commit bbb62c0b024a ("sched/core: Remove
the rt_avg code"). The comment about compiler optimization of
this non-existent function is no longer relevant.
2. The sched_class callback ->select_task() was renamed to
->select_task_rq() long ago. Update the comment to match.
