Description of problem:
A directory containing linkto files that point to itself cannot be deleted.


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


How reproducible:

Consistently

Steps to Reproduce:

1. gluster v create tvol 192.168.122.7:/bricks/brick2/tvol-{1..2}
2. gluster v start tvol
3. mount -t glusterfs -s 192.168.122.7:/tvol /mnt/g1
4. cd /mnt/g1
5. mkdir -p dir0/dir1/dir2
6. cd dir0/dir1/dir2
7. for i in {1..100}; do echo "Test file" > tfile-$i; done
8. for i in {1..100}; do mv tfile-$i ntfile-$i; done
9. gluster v remove-brick tvol 192.168.122.7:/bricks/brick2/tvol-2 start

Once the remove-brick status shows "completed", 
10. gluster v remove-brick tvol 192.168.122.7:/bricks/brick2/tvol-2 stop

You should now have only linkto files in 192.168.122.7:/bricks/brick2/tvol-2/dir0/dir1/dir2 and they should all be pointing to 
tvol-client-0. 
Manually change the linkto xattr value for every file in brick2 to point to itself, in this case "tvol-client-1"(make sure the string is null terminated).

11. setfattr -n trusted.glusterfs.dht.linkto -v 0x74766f6c2d636c69656e742d3100 /bricks/brick2/tvol-2/dir0/dir1/dir2/ntfile-*

12. Try to delete the directory from the mount point:

[root@myserver g1]# rm -rf *


Actual results:

[root@myserver g1]# rm -rf *
rm: cannot remove ‘dir0/dir1/dir2’: Directory not empty

Expected results:

The directory should be deleted as there are no data files inside.
