Description of problem:  In A cascaded setup, rm -rf on master didn't completely propagated to level 2 slave. 

imaster(intermediate master) geo-rep logs had some trace-backs.

Version-Release number of selected component (if applicable): glusterfs-3.6.0.27-1.el6rhs


How reproducible: Didn't try to reproduce the issue


Steps to Reproduce:
1. create and start a geo-rep cascaded setup between master, imaster and slave.
2. create some data on master and let it sync to imaster and slave.
3. then rm -rf on master mount-point. 
4. Check if it succeeds to remove from the slave. 

Actual results: rm -rf on master fails to propagate to slave level 2 


Expected results: rm -rf on master  should be remove all the files from all the slaves.
