+++ This bug was initially created as a clone of Bug #1563511 +++

Description of problem:

COMMIT: https://review.gluster.org/19818 committed in release-3.12 by "jiffin tony Thottan" <jthottan> with a commit message- cluster/dht: act as passthrough for renames on single child DHT

Various synchronization present in dht_rename while handling
directories and files is necessary only if we have more than only one
child.
