+++ This bug was initially created as a clone of Bug #1207979 +++

Description of problem:
=======================
If file is edited from NFS mount then Version is not incremented and bitd is
not updating checksum for file

Version-Release number of selected component (if applicable):
=============================================================
0.803.gitf64666f.el6.x86_64

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

Steps to Reproduce:
===================
1. create and NFS mount volume.
2. enable bitrot
3. create few files.
4. Update file from NFs mount and check version and checksum

on client:-
[root at rhs-client44 linux-3.19]# mount | grep nfs
rhs-client44.lab.eng.blr.redhat.com:/rac1 on /mnt/rac1 type nfs
(rw,addr=10.70.36.68)

On server:- 
[root at rhs-client44 linux-3.19]# getfattr -d -m . -e hex /pavanbrick6/r1/f5
getfattr: Removing leading '/' from absolute path names
# file: pavanbrick6/r1/f5
trusted.gfid=0x3f396fffe3754fa8ba6a62afc00b39a4
trusted.glusterfs.bit-rot.signature=0x01000000000000000100000000000000e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
trusted.glusterfs.bit-rot.version=0x0100000000000000551a639300053ca4

from client:-
[root at rhs-client44 linux-3.19]# echo "abc" >> /mnt/rac1/f5

verify on server:-
[root at rhs-client44 linux-3.19]# getfattr -d -m . -e hex /pavanbrick6/r1/f5
getfattr: Removing leading '/' from absolute path names
# file: pavanbrick6/r1/f5
trusted.gfid=0x3f396fffe3754fa8ba6a62afc00b39a4
trusted.glusterfs.bit-rot.signature=0x01000000000000000100000000000000e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
trusted.glusterfs.bit-rot.version=0x0100000000000000551a639300053ca4

Actual Result:-
===============
Object version is not incremented and checksum is not updated

Expect Result:-
===============
On modification it should increment object version and re calculate
