The 'replay-log' executable will replay the dm-log-writes log until the given mark, or until the end of the log if the mark isn't found. This means that if the mark you're looking for was never inserted in the log or if you give garbage to _log_writes_replay_log() the entire log will be replayed. This can cause unexpected test results. Fix this by making sure that the mark we're given actually exists in the log before we allow the replay.
