  ndb - bug#22893
    Add checking of REDO to earlier during SR
        so take-over of node can be performed
        if it can't be restarted using logs
        (which btw is really weird...as it _should_ be able to use logs of other node in node group)
  
    Otherwise cluster could be started and 1 fragment on one node could not have been restored
    Making the cluster inconsisten, VERY BAD
