When we fixed the last bug in the virt_platform node_exporter metric, we accidentally broke the type="none" calculation. We need to fix this and back port to 4.2.
since we can not always get virt_platform{type="none"} for testing cluster,tested locally with the fix, no issue now 4.4.0-0.nightly-2020-01-13-010304
