Description of problem:
issue is that I am getting different values of quota stats from quota list comamnd on different nodes of the cluster.

Version-Release number of selected component (if applicable):
glusterfs-3.4.0.44rhs-1

How reproducible:
seen for more than one directory

Steps to Reproduce:
1. create a volume, start it
2. enable quota
3. mount it over nfs
4. create few thousand directories. say 1000

5. being a having set up of four nodes[1-4] cluster, stop glusterd and kill brick processes on node 2 and node 4

6. on each directory set limit of 10GB
7. start creating data inside the these directories, till their individual limit is not reached.
8. start glusterd on nodes 2 and 4, this will bring the bricks also back
9. take quota stats using quota list command, on all the nodes.


Actual results:
result after step 9.,
from node1,
                  Path                   Hard-limit Soft-limit   Used  Available
--------------------------------------------------------------------------------
/57                                       10.0GB       80%       4.5GB   5.5GB

from node2,
[root@quota6 ~]# gluster volume quota dist-rep list /57
                  Path                   Hard-limit Soft-limit   Used  Available
--------------------------------------------------------------------------------
/57                                       10.0GB       80%       5.5GB   4.5GB

from node3,
[root@quota7 ~]# gluster volume quota dist-rep list /57
                  Path                   Hard-limit Soft-limit   Used  Available
--------------------------------------------------------------------------------
/57                                       10.0GB       80%      10.0GB  0Bytes

from node4,
[root@quota8 ~]# gluster volume quota dist-rep list /57
                  Path                   Hard-limit Soft-limit   Used  Available
--------------------------------------------------------------------------------
/57                                       10.0GB       80%      0Bytes  10.0GB


Also for some directories the information is different on same node on each invocation of quota list command


Expected results:
The info at one time remain same for a certain directory on all nodes.
Also, each invocation of quota list command the result should be same not different.

Additional info:
After invoking "find . | xargs stat" on the nfs mount-point after almost an hour of step9 mentioned in "Steps to Reproduce" section, the result our found to be good.

Presently, considering this issue may be related to self-heal taking time.
