In push_submodule(), because we do not actually need access to objects
in the submodule, do not invoke add_submodule_odb().
(for_each_remote_ref_submodule() does not require access to those
objects, and the actual push is done by spawning another process,
which handles object access by itself.)

This code of push_submodule() is exercised in t5531 and continues
to work, showing that the submodule odbc is not needed.
