Topic table partition generator is a simple helper to asynchronously iterate over a topic table which may have a lot of elements. The generator validates if `topic_table` changed while the loop yield for the other tasks. The check was incorrect as it was validating the topic table revision which is updated after the snapshot is applied. Fixed the issue by validating it `_topics_map_revision` changed during the scheduling point. Fixes: #core-internal/1259 Signed-off-by: Michał Maślanka <michal@redpanda.com> (cherry picked from commit 14726e2)
