What problem does this PR solve?

Issue Number: close #46545

Problem Summary:

What is changed and how it works?

After #39041 the row id and auto increment id use different key.
Here IncrementID should be used.

Check List

Tests

  • Unit test
  • Integration test
  • Manual test (add detailed scripts or steps below)

Follow the step in issue #46545
It's not easy to integration test for this, since the bug need a tidb restart to trigger.
After the autoid service initialized, the cached value is used and the code logic does not go the buggy line.

Hi @tiancaiamao. Thanks for your PR.

PRs from untrusted users cannot be marked as trusted with /ok-to-test in this repo meaning untrusted PR authors can never trigger tests themselves. Collaborators can still trigger tests on the PR using /test all.

I understand the commands that are listed here.
