Description of problem:
listing of snaps created before a directory gives "Stale file handle" when listed from /mnt/dir/.snaps from NFS mount.

Version-Release number of selected component (if applicable):
glusyterfs-3.7.5-19

How reproducible:

1.Create a volume and mount it using NFS
2.Enable USS on the volume and create and activate 2 snapshots; snap1 and snap2
3.Create a directory say dir1

5.cd  to /mnt/dir1/.snaps and do a ls -l on it, Observe that snap1 and snap2 are listed as below:

[root@dhcp35-15 .snaps]# ls -ltr
ls: cannot access snap1: Stale file handle
ls: cannot access snap2: Stale file handle
total 0
??????????? ? ?    ?     ?            ? snap2
??????????? ? ?    ?     ?            ? snap1
drwxr-xr-x. 2 root root 18 Feb 12  2016 snap4
drwxr-xr-x. 2 root root 18 Feb 12  2016 snap3

Actual results:
