Description of problem:

In OCPBUGS-30951, we modified a check used in the Cinder CSI Driver Operator to relax the requirements for enabling topology support. Unfortunately in doing this we introduced a bug: we now attempt to access the volume AZ for each compute AZ, which isn't valid if there are more compute AZs than volume AZS. This needs to be addressed.

Version-Release number of selected component (if applicable):

This affects 4.14 through to master (unreleased 4.17).

How reproducible:

Always.

Steps to Reproduce:

1. Deploy OCP-on-OSP on a cluster with fewer storage AZs than compute AZs

Actual results:

Operator fails due to out-of-range error.

Expected results:

Operator should not fail.

Additional info:

None.
