orangefs: turn param response value into union
This will support a upcoming request where two related values need to be updated atomically. This was done without a union in the OrangeFS server source already. Since that will break the kernel protocol, it has been fixed there and done here in a way that does not break the kernel protocol. Signed-off-by: Martin Brandenburg <martin@omnibond.com>
