dm io: retry after barrier error If -EOPNOTSUPP was returned and the request was a barrier request, retry it without barrier. Retry all regions for now. Barriers are submitted only for one-region requests, so it doesn't matter. (In the future, retries can be limited to the actual regions that failed.)
