Description of problem:
========================
We are able to get the "trusted.glusterfs.quota.limit-set" extended-attribute from the client machine

Version-Release number of selected component (if applicable):
==============================================================
glusterfs 3.4.0.35rhs built on Oct 15 2013 14:06:04

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

Steps to Reproduce:
=======================
1. Create a replicate volume. Start the volume. 

2. Enable quota on the volume. Set limit-usage on "/" for 1GB

3. From the client machine mount the volume. 

4. Execute : "getfattr -d -e hex -m . <mount_point>"

Actual results:
================
root@darrel [Oct-17-2013-12:54:00] >mount -t glusterfs rhs-client11:/vol_rep /mnt/fuse2

root@darrel [Oct-17-2013-12:54:12] >getfattr -d -e hex -m . /mnt/fuse2
getfattr: Removing leading '/' from absolute path names
# file: mnt/fuse2
trusted.glusterfs.quota.limit-set=0x0000000280000000ffffffffffffffff
trusted.glusterfs.volume-id=0x5a934afaff4448568f4032572ed0850f


Expected results:
=================
None of the trusted.glusterfs* attributes should be visible.
