    cluster/dht: Fix dht_access treating directory like files
    
    When the cluster topology changes due to add-brick, all sub
    volumes of DHT will not contain the directories till a rebalance
    is completed. Till the rebalance is run, if a caller bypasses
    lookup and calls access due to saved/cached inode information
    (like NFS server does) then, dht_access misreads the error
    (ESTALE/ENOENT) from the new subvolumes and incorrectly tries
    to handle the inode as a file. This results in the directories
    in memory state in DHT to be corrupted and not heal even post
    a rebalance.
    
    This commit fixes the problem in dht_access thereby preventing
    DHT from misrepresenting a directory as a file in the case
    presented above.
