A checksum error in `mariadb-binlog --verify-binlog-checksum --force-read` previously resulted in both an error message and an Unknown event substitute, the latter of which failed an assertion in debug builds or became forgotten (memory leak) in non-debug (release) builds. Since `mariadb-binlog --force-read` outputs “Unknown event”s rather than errors in other invalid event cases, this commit removes the error status from this situation to match.
