    glusterd: fix info file checksum mismatch during upgrade
    
    issue: probing a new  node(>=3.6)  from 3.5 cluster is moving the peer to rejected state.
    
    fix: Disperse vol support is added from 3.6 release, so write disperse fields (disperse_count=0
    and redundancy_count=0) in vol info file  only if cluster version supported.
