libglusterfsclient: Move DHT root-lookup workaround to init
The workaround for the DHT requirement for a lookup on /
needs to be done only once when the xlator graph is inited.
Doing it on every path's lookup results in a major performance
penalty when using distribute subvolumes upwards of 16, as reported
by Avati.
