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
