Disk image formats that wish to opt-out of version validation are supposed to set versionOffset to -1 in their fileTypeInfo entry. By unconditionally returning False for these formats, virStorageFileMatchesVersion() incorrectly reports a version mismatch when the test was actually skipped. The correct behavior is to return True so these formats can be successfully probed using the magic bytes alone.
