    md-cluster: show array's status more accurate · 0357ba27

    When resync or recovery is happening in one node,
    other nodes don't show the appropriate info now.
    
    For example, when create an array in master node
    without "--assume-clean", then assemble the array
    in slave nodes, you can see "resync=PENDING" when
    read /proc/mdstat in slave nodes. However, the info
    is confusing since "PENDING" status is introduced
    for start array in read-only mode.
    
    We introduce RESYNCING_REMOTE flag to indicate that
    resync thread is running in remote node. The flags
    is set when node receive RESYNCING msg. And we clear
    the REMOTE flag in following cases:
    
    1. resync or recover is finished in master node,
       which means slaves receive msg with both lo
       and hi are set to 0.
    2. node continues resync/recovery in recover_bitmaps.
    3. when resync_finish is called.
    
    Then we show accurate information in status_resync
    by check REMOTE flags and with other conditions.
