Description of problem: quota command fails for directory with colon in its name


Version-Release number of selected component (if applicable): Glusterfs_3.2.6-1


How reproducible: Always


Steps to Reproduce:

1. Set disk limit for a directory with colon in its name:

# gluster volume quota testeGluster limit-usage /domain/users/teste\:cal 5GB 

  
Actual results: 

Display disk limit:

# gluster volume quota testeGluster list 

  path          limit_set         size
----------------------------------------------------------------------------------

/domain          30GB
/domain/users/abacate       10GB
/domain/users/adailton       10GB
/domain/users/adiministrativo       10GB
/domain/users/administrativo       10GB
/domain/users/agv       10GB
/domain/users/teste    cal:5GB
.
.
umount: /tmp/mntjJiIDt: not mounted

Quota command fails to show disk usage for all directories. Besides, the directory name (teste:cal) appears with blank spaces and below the list there is this message: "umount: /tmp/mntjJiIDt: not mounted" 




Expected results:

~# gluster volume quota testeGluster list


    path          limit_set         size
----------------------------------------------------------------------------------

/domain          30GB               12.2GB
/domain/users/abacate       10GB              376.0KB
/domain/users/adailton       10GB                2.1MB
/domain/users/adiministrativo       10GB               0Bytes
/domain/users/administrativo       10GB               0Bytes
/domain/users/agv       10GB              184.0KB
/domain/users/teste:cal       5GB        2GB


Additional info:

After removing the limit of the directory with colon, quota list command displays the size again.
