We expect \Device\HarddiskVolumeX... in convert_NT_to_Dos_path() -- but we
already have a DOS relative path here.

OK, that's just the post-section-map, using NtQueryInformationFile
FileNameInformation. xref issue #138 notes.

At map time, using MemorySectionName (get_mapped_file_name()), we get the
NT path, which we do convert successfully:

We should quite this warning at post-section-open.
