As a principle, it's probably fine that an "immediate" cs would have
some additional data that a deferred cs doesn't. I'd suggest to split
that the same way we do in other places though. E.g.:

    struct wined3d_cs
    {
       const struct wined3d_cs_ops *ops;
       ...
    };

    struct wined3d_cs_immediate
    {
       struct wined3d_cs c;
       ...
       struct wined3d_state state;
       ...
    };

    struct wined3d_cs_mt
    {
       struct wined3d_cs_immediate c;
       ...
       HANDLE thread;
       ...
    };
