Description of problem:
Long back when GlusterFS was in still Alpha state (may be 1.3.x releases), we had a feature to create/edit a file, read a file using setxattr()/getxattr() syscalls.
Currently some part of the code is present in posix.c but its not getting hit at all. (found during code-coverage runs)

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

How reproducible:
everytime.


Steps to Reproduce:
1. Make sure its a empty mountpoint, with just one brick in volume (ls /mnt/glusterfs)

2. bash# setxattr -n glusterfs.file.testfile -v "helloworld" /mnt/glusterfs

3. bash# cat /mnt/glusterfs/testfile (should show 'helloworld' as content).
  
Actual results:
setxattr command fails

Expected results:
The above sequence of commands should work fine.
