Detail: adding sync status for cluster device

On the node with /proc/mdstat is

Personalities : [raid1]
md0 : active raid1 sdb[4] sdc[3] sdd[2]
      1046528 blocks super 1.2 [3/2] [UU_]
        recover=REMOTE
      bitmap: 1/1 pages [4KB], 65536KB chunk

Let's change the 'State' of 'mdadm -Q -D' accordingly
State : clean, degraded
With this patch, it will be
State : clean, degraded, recovering (REMOTE)
