[PATCH v3 15/27] revisions API users: use release_revisions() for "prune_data" users

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Use release_revisions() for users of "struct rev_list" that reach into
the "struct rev_info" and clear the "prune_data" already.

In a subsequent commit we'll teach release_revisions() to clear this
itself, but in the meantime let's invoke release_revisions() here to
clear anything else we may have missed, and for reasons of having
consistent boilerplate.
