Fix wrong skipf parameter

**How to reproduce**

When run e2e test, it reports `%!!(MISSING)d(MISSING)`:
```
STEP: Checking for multi-zone cluster.  Zone count = 1
Dec  6 14:16:43.272: INFO: Zone count is %!!(MISSING)d(MISSING), only run for multi-zone clusters, skipping test
[AfterEach] [k8s.io] Multi-AZ Clusters
```

We need to pass a string parameter to `SkipUnlessAtLeast`
