Here, we only set suboid if !update_data->just_cloned...

...and here, we read suboid if !update_data->just_cloned.

And here we declare it with no initializer. This is safe for now since we only
read it when !update_data->just_cloned, which is also the condition for setting
it, but may be error-prone in the future. Probably best to initialize it to
something.
Other than that everything looks good up to and including this patch. This is
definitely an improvement over using a null OID to signal something, so thanks.
