bugfix: change log level from error to info

[caozhuozi]

I'm not sure why the code uses Errorf here while the result of parseSymbolReference is ok.

I found this issue when I was using openapi-gen.go to generate the /test/integration/testdata/defaults package (to have a try) and the following error logs appeared.

E0322 16:21:36.249229   11020 openapi.go:707] k8s.io/kube-openapi/test/integration/testdata/defaults.ConstantValue, k8s.io/kube-openapi/test/integration/testdata/defaults
E0322 16:21:36.249997   11020 openapi.go:707] k8s.io/kube-openapi/test/integration/testdata/defaults.ConstantValue, k8s.io/kube-openapi/test/integration/testdata/defaults

But the files were generated successfully.

Hope I don't have any misunderstanding here.

Thanks for catching this. That makes sense, will leave lgtm to Alex. If anything this seems more like a debug statement that wasn't taken out? Do we need a proper comment rather than just logging id and commentPath?

Thanks @Jefftree ! Yes, it looks like a debug statement. Let's see if @alexzielenski could give any suggestions about the logging context.

It likely is a debug statement. I'm ok with it being removed also, Infof seems fine
