Description of problem:
=======================
File permission got changed after file migration in few cases.


before rebalance:-
[root@dht19 test]# ls -l
total 0
-rwSr--r-- 1 root root 0 Nov 11 09:27 ooo

After rebalance:-
[root@dht19 test]# ls -l
total 0
-rw-r--r-- 1 root root 0 Nov 11 09:27 ooo


before rebalance:-
 [root@dht19 test]# ls -l
 total 0
-rwxr-sr-- 1 root root 0 Nov 11 09:27 ooo

After rebalance:-
[root@dht19 test]# ls -l
 total 0
-rwxr-xr-- 1 root root 0 Nov 11 09:27 ooo
 

Version-Release number of selected component (if applicable):
=============================================================
3.6.0.29-1.el6rhs.x86_64


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

Steps to Reproduce:
===================
1. create, start and FUSE mount Distributed volume having 3 bricks. 
2. created file,  renamed it so hashed and cached sub-volumes are different and change permission as below

case 2:-
[root@dht19 test]# ls -l
 total 0
-rwxr-sr-- 1 root root 0 Nov 11 09:27 ooo


3. started rebalance process for that volume. Once rebalance is completed.

4. checked file from mount point it has different permission.

case 1:-
[root@dht19 test]# ls -l
total 0
-rw-r--r-- 1 root root 0 Nov 11 09:27 ooo


case 2:-
After rebalance:-
[root@dht19 test]# ls -l
