What problem does this PR solve?

Issue Number: ref #55563

Problem Summary:

What changed and how does it work?

In #57042, I add too much calls of ensureActiveUser() than necessary. That's introduced to make the CI pass.
That PR had already done a lot to make the CI pass .... So I don't like to introduce extra complexity to it.

After merge that, this commit will be used to reduce some unnecessary ensureActiveUser().

Check List

Tests

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

For example

Without optimizing the unnecessary ensureActiveUser(), If I use set password for user%d to change password for 2M users, here is the QPS

After the optimization:

• No need to test

  • I checked and no code files have been changed.

Side effects

• Performance regression: Consumes more CPU
• Performance regression: Consumes more Memory
• Breaking backward compatibility

Documentation

• Affects user behaviors
• Contains syntax changes
• Contains variable changes
• Contains experimental features
• Changes MySQL compatibility
