Description of problem:
=======================
Linkto files which were created during rebalance are also being counted in inode-quota limit.

Version-Release number of selected component (if applicable):
3.8.4-14.el7rhgs.x86_64

How reproducible:
always

Steps to Reproduce:
===================
1) Create a distributed-replicate volume and start it.
2) Enable quota on the volume, "gluster volume quota <vol-name> enable".
3) FUSE mount the volume.
4) Set the inode limit on the volume, 
gluster v quota <vol-name> limit-object / 1500
5) Start creating 1600 files on the mount point
for i in {1..1600}; do cat /etc/redhat-release > f$i;done
6) While file creation is in-progress, add few bricks and trigger rebalance.
7) Wait till the step-5 and step-6 completes
8) Check the file count on the mount point ---> There were 1440 created files
9) Check the files count in "list-objects" output --->  The files count was 1497

[root@node1 ~]# gluster v quota distrep list-objects
                  Path                   Hard-limit   Soft-limit      Files       Dirs     Available  Soft-limit exceeded? Hard-limit exceeded?
-----------------------------------------------------------------------------------------------------------------------------------------------
/                                             1500       80%(1200)       1497         3           0             Yes                  Yes

There is a mismatch of files count between mount point and list-objects output.

Here is some anayalsis for the file count mismatch,
Total list-objects files count : 1497
Total number of link to files created on bricks during rebalance : 57

1497 - 57 = 1440 which is the total files count on the mount point

Actual results:
===============
Linkto files which got during rebalance are also being counted in inode-quota limit

Expected results:
=================
In the list-objects output, we should not count linkto files (hashed files) as we are already count cached files.
