geo-rep: Do not fail-back to xsync if Changelog is failed
Unless change_detector is set to xsync, do not fallback to xsync, except during Initial Sync or Partial History. When a brick goes down, Changelog exception is raised due to which geo-rep fallback to xsync. Even after brick comes back geo-rep will not consume Changelog.
