orangefs: record userspace version for feature compatbility
The client reports its version to the kernel on startup. We already test that it is above the minimum version. Now we record it in a global variable so code elsewhere can consult it before making a request the client may not understand. Signed-off-by: Martin Brandenburg <martin@omnibond.com>
