Improve error handling in OBJ_add_object()

There is no need for a helper function to obfuscate lh_ADDED_OBJ_new().
Just call the real thing directly.

Adding an object with a NID of NID_undef basically amounts to disabling
a built-in OID. It does so in an incoherent fashion and the caller can't
easily tell success from failure of the operation. Arguably the result is
a corrupted objects table.

Let's not allow adding such an object in an attempt at keeping things
slightly more coherent.
