remove vkuzo from CODEOWNERS for AO (pytorch#86038)

Summary:

I was added to various places in pytorch#79505, this is
too noisy to be useful so taking myself off.  Always happy to help when folks tag me
manually.

Test plan: CI
Pull Request resolved: pytorch#86038
Approved by: https://github.com/HDCharles
