pack-objects: drop unused rev_info parameters

When collecting the list of objects to pack in get_object_list(), we
pass our rev_info struct around to some functions that don't need it.
This is due to 03a9683 (Simplify is_kept_pack(), 2009-02-28), where
the kept-pack handling was moved out of the revision machinery.

Let's drop these unused parameters.
