When online alter rollbacks due to MDL time out, it doesn't mark the index online status as ONLINE_INDEX_ABORTED. Concurrent update fails to update the secondary index while building the entry. InnoDB should check the online status of the secondary index before building the secondary index entry. Reviewed-by: Marko Mäkelä
