ttl: fix the issue that the TTL jobs are skipped or handled multiple times in one iteration

[YangKeao]

What problem does this PR solve?

Issue Number: close #59347
Problem Summary:

Some of the TTL jobs are skipped for handled multiple times in one iteration. It caused the following effect:

1. It'll take more time for CheckNotOwnedJob, checkFinishedJob, rescheduleJobs to handle all existing jobs.
2. The last job may be handled for multiple times, like finished multiple times.

I think it's a minor issue as both of them don't block the TTL.

What changed and how does it work?

Iterate the jobs in the reverse order.

NO. @lcwangchao told me it'll also flush all statistic data of a TTL job if a job is finished multiple times 🤦 .
