glusterd/snapshot : Remove the barrier key from snap volinfo
before generating brick volfile.
Problem : During snapshot creation if I/O is in progress,
then barrier value is enabled. Hence during snapshot create
and in-turn snapshot restore the barrier value is set to enable.
Because of this further I/O on the mount point fails.
Solution : Remove the barrier key from newly created snap volinfo
before generating the brick volfiles.
