Currently, creating a volume with replication group_id, the volume
creates successfully, but it isn't added to storwize replication group.
Creating a volume with hyperswap group_id has the same problem.
Since adding a volume to a replication group immediately follow the
volume creation may be failed on storwize, this patch disables creating
volume with non cg_snapshot group_id.
