Description of problem:
======================
After rename, we are seeing both the source file and destination file when the below steps are performed which is not expected, 

Version-Release number of selected component (if applicable):
3.8.4-5.el7rhgs.x86_64

How reproducible:
=================
Always

Steps to Reproduce:
===================
1) Create a disperse volume and start it.
2) FUSE mount the volume on a client.
3) Create a file say f1.
4) Identify a brick on which the file 'f1' is hashed and bring down that brick by killing it process.
5) Now, rename the file from 'f1' to 'rename_f2'. From mount point we will be seeing the renamed file.
6) Bring back the killed brick and check the mount point.

We will be seeing both the original file and renamed file.
