ROCm SMI CLI: Force RETCODE to 0 by Default

The purpose of this patch is to set RETCODE equal to 0 by default
unless an appropriate '--loglevel LEVEL' has been set.

To allow a non-zero RETCODE value, you must use any loglevel that
is not 'warning' or 'None' (default).

You can set the loglevel in the CLI with:
--loglevel <debug/info/warning/error/critical>
