When recovering from various RQG workloads, maria_read_log reported the following:

The transaction log starts from lsn (3,0x2926)
TRACE of the last maria_read_log
/home/buildbot/rqg-buildbot-slave/rqg-weekend/build/mysql-test//../storage/maria/maria_read_log: Maria engine: starting recovery

/home/buildbot/rqg-buildbot-slave/rqg-weekend/build/mysql-test//../storage/maria/maria_read_log: Maria engine: recovery done
maria_read_log: DOUBTFUL (1 warnings, check previous output)

Apart from the underlying issue, maria_read_log returned 0, whereas instead this should have been a clear failure and the script should have returned a non-zero failure code.
