Fix user visible files creation for windows
**What this PR does / why we need it**:
Fix user visible files creation for windows. Without this, [createUserVisibleFiles](https://github.com/kubernetes/kubernetes/blob/master/pkg/volume/util/atomic_writer.go#L415:24) will get linkname with subpath included, and then symlink will fail. This is because "/" is used in pod spec (e.g. `"new/path/data-1"`) while "\" is used on Windows to get linkname.
