[libvirt] [PATCH 1/4] Allow probing of image formats without version information
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.
