Description of problem:

Whenever rename operations are done inside the root directory of the volume, an extra root inode is created in the inode table.

This is the o/p of gluster volume status <volname> inode, indicating the leak.

How reproducible:

always

Steps to Reproduce:
1. create a volume, start it and mount it.
2. cd into the root of the volume, create an entry
3. rename the entry
  
Actual results:

extra inode is created for root, whenever rename operation is done on an entry present in the root directory of the volume (doing rename operation on a entry present in some other directory of the volume does not cause inode leak).

Expected results:

for rename operation extra inode should not be created for root.
