revisions API users: use release_revisions() needing REV_INFO_INIT
Use release_revisions() to various users of "struct rev_list" which
need to have their "struct rev_info" zero-initialized before we can
start using it.
For the bundle.c code see the early exit case added in
3bbbe467f29 (bundle verify: error out if called without an object
database, 2019-05-27).
For the relevant bisect.c code see 45b6370812c (bisect: libify
`check_good_are_ancestors_of_bad` and its dependents, 2020-02-17).
For the submodule.c code see the "goto" on "(!left || !right || !sub)"
added in 8e6df65015f (submodule: refactor show_submodule_summary with
helper function, 2016-08-31).
