commit b8f3aab95f01ac7d590a5ba490e890d9cf8c2e50
Author: Susant Palai <spalai>

    DHT/readdirp: Directory not shown/healed on mount point if exists
                  on single brick(non first up subvolume).
    
    Problem: If snapshot is taken, when mkdir has succeeded only on
    hashed_subvolume, then after restoring snapshot the directory
    is not shown on mount point.
    
    Why:    dht_readdirp takes only those directory entries in to
    account, which are present on first_up_subvolume. Hence, if the
    "hashed subvolume" is not same as first_up_subvolume, it wont be listed
    on mount point and also not healed.
    
    Solution:
    Case 1: (Rebalance not running)If hashed subvolume is NULL or down then
    filter in first_up_subvolume. Other wise the corresponding hashed subvolume
    will take care of the directory entry.
    
    Case 2: If readdirp_optimize option is turned on then read from first_up_subvol
