    xfs_repair: set rsumino version to 2
    
    If we run xfs/033 with "-m crc=0", the test fails with a repair
    output difference:
    
         Phase 7 - verify and correct link counts...
        +resetting inode INO nlinks from 0 to 1
         done
    
    This is because when we zero out the realtime summary inode and
    rebuild it, we set its version to 1, then set its ip->i_d.di_nlink
    to 1.  This is a little odd, because v1 inodes store their link
    count in di_onlink...
    
    Then, later in repair we call xfs_inode_from_disk(), which sees the
    version one inode, and converts it to version 2 in part by copying
    di_onlink to di_nlink.  But we never *set* di_onlink, so di_nlink
    gets reset to zero, and this error is discovered later in repair.
    
    Interestingly, mk_rbmino() was changed in 138659f1 to set version 2;
    it looks like mk_rsumino was just missed.
