Description of problem:  When gluster volume delete is run and removes the volume it leaves behind xattrs that cause a gluster volume create to fail.

Version-Release number of selected component (if applicable):

glusterfs-server-3.3.0rhs-25.el6rhs.x86_64

How reproducible:

Every time.

Steps to Reproduce:
1.  Run gluster volume delete on a volume
2.  Try to create a new volume using the brick from a deleted volume
3.
  
Actual results:

***From the command line***
Create: 
[root@hp-dl380g7-1 distributed-volume-setup]# gluster volume create distributed-volume hp-dl380g7-1.gsslab.rdu.redhat.com:/brick1 hp-dl380g7-2.gsslab.rdu.redhat.com:/brick1 
Creation of volume distributed-volume has been successful. Please start the volume to access data.

Delete: 
[root@hp-dl380g7-1 distributed-volume-setup]# gluster volume delete distributed-volume 
Deleting volume will erase all information about the volume. Do you want to continue? (y/n) y Deleting volume distributed-volume has been successful

And create again: 
[root@hp-dl380g7-1 distributed-volume-setup]# gluster volume create distributed-volume hp-dl380g7-1.gsslab.rdu.redhat.com:/brick1 hp-dl380g7-2.gsslab.rdu.redhat.com:/brick1 
/brick1 or a prefix of it is already part of a volume

Expected results:

The xattrs are properly cleared so that a volume create can be executed without manually clearing them.
