Return WARNING/CRITICAL in maintenance mode only

Using the "maintwarn" option, the script would return with exit code 1, even if the system was not in maintenance mode. Without that option, the script would fail because $addopts is undefined. A workaround is to use -o "". Alternatively, // '' could be added to line 512.
