Release NodePorts at the end of test cases
**What this PR does / why we need it**:
#49098 reported a flake of HealthCheck NodePort leak and #49099 fixed it. I don't know why I forgot to check other Node Ports in the test cases. Though I haven't encountered such flake yet, it'd be good to release those Node Ports at the end of test cases to avoid flake.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#49548
