In ON mode, error pointer is passed to errp and logged. In OFF mode, we doesn't need to log "Migration disabled" as it's intentional. In AUTO mode, we should only ever see errors or warnings if the device supports migration and an error or incompatibility occurs while further probing or configuring it. Lack of support for migration shoundn't generate an error or warning.
