    cluster/tier: Do not delete linkto file on demotion
    
    The current DHT migration code will always delete the
    src linkto file after migration as dht always moves
     files to the hashed subvol. This is not the case in tiering.
    The lack of linkto files causes rename to fail leaving 2 files
     with the same name but different gfids on the volume.
    Modified to leave the linkto file behind if the source
     volume is the hashed subvolume.
