ip_tunnel: return more precise errno value when adding tunnel fails Currently this always returns ENOBUFS, because the return value of __ip_tunnel_create is discarded. A more common failure is a duplicate name (EEXIST). Propagate the real error code so userspace can display a more meaningful error message.
