    dht/rebalance: Do not allow rebalance when gfid mismatch found
    
    Due to race condition, it may so happen that, gfid obtained
    in readdirp and gfid found by lookup are different for a given
    name. in that case do no allow the rebalance.
    
    Readdirp of an entry will bring the gfid, which will be stored
    in the inode through inode_link, and when lookup is done and
    gfid brought by lookup is different from the one stored in the
    inode, client3_3_lookup_cbk will return ESATLE and error will be
    captured by rebalance process.
