fast-export: Set revs.topo_order before calling setup_revisions

setup_revisions sets a variety of flags based on the setting of other
flags, such as setting the limited flag when topo_order is set.  To avoid
circumventing any invariants created by setup_revisions, we set
revs.topo_order before calling it rather than after.
