The default_log(/var/log/cxl-monitor.log) should be used when no '-l'
argument is specified in daemon mode, but it was not working at all.

Here we assigned it a default log per its arguments, and simplify the
sanity check so that it can be consistent with the document.

Please note that i also removed following addition stuff, since we have
added this prefix if needed during parsing the FILENAME in
parse_options_prefix().
if (strncmp(monitor.log, "./", 2) != 0)
    fix_filename(prefix, (const char **)&monitor.log);
