We can't fallback unconditionally when GetFinalPathNameByHandle fails. The only reason for this fallback path is for cases where there is a sym link to something that we know doesn't support links. So this is why it is limited to ERROR_INVALID_LEVEL, and even then it is dubious and maybe we need to explore the errors and interop issues further before seeing if anything should be done.
