Problem:

 1. When --expire_logs_days and --binlog-expire-logs-seconds are set
    to conflicting values, and the binary log is disabled, the warning
    for the conflicting values was not issued and the values were not
    corrected.

 2. There was no warning when using either of these options when the
    binary log is disabled. This differs from other options that are
    void when the binary log is disabled, such as --binlog-format and
    --log-slave-updates

Fix:

 1. Check the conflicting values of these options even when the binary
    log is disabled.

 2. Generate a warning if any of these options is used when the binary
    log is disabled.
