Description of problem:
If a subdirectory is having quota limit set as well as it's parent directory has quota limit set and given the condition that quota-deem-statfs is on then "df -h <path to dir/subdir>"
displays the result as per limits set for that dir/subdir.

Whereas this time stats displayed are only for the parent even if one executes "df -h <path to subdir>"



Version-Release number of selected component (if applicable):
glusterfs-3.6.0.28-1.el6rhs.x86_64

How reproducible:
happen to be seen on build

Steps to Reproduce:
1. create a volume of 6x2 type, start it
2. enable quota limit on the volume
3. mount the volume over nfs
4. create a directory inside the mount-point, namely "dir1"
5. set different quota limit for "/" and "dir1"
6. df -h <mount-point> --- works as expected
7. df -h <mount-point/dir1> --- does not work as expected

Actual results:
[root@nfs1 ~]# gluster volume quota dist-rep list
                  Path                   Hard-limit Soft-limit   Used  Available  Soft-limit exceeded? Hard-limit exceeded?
---------------------------------------------------------------------------------------------------------------------------
/                                         20.0GB       80%      18.7GB   1.3GB             Yes                   No
/dir1                                      5.0GB       80%       5.0GB  0Bytes             Yes                  Yes

step6 result,
[root@rhsauto002 dir3]# df -h /mnt/nfs-test
Filesystem             Size  Used Avail Use% Mounted on
10.70.37.156:dist-rep   20G   19G  1.3G  94% /mnt/nfs-test

step7, result

[root@rhsauto002 dir3]# df -h /mnt/nfs-test/dir1
Filesystem             Size  Used Avail Use% Mounted on
10.70.37.156:dist-rep   20G   19G  1.3G  94% /mnt/nfs-test


Expected results:
step 7 should display "Size" field as 5GB and "Used" field as 5GB

Hence, things don't match from build 27 to build 28 itself.
