Bugfix Pull Request

Can't delete a value in mod_dir_config. I'm getting a "syntax error" response.

Example: hpilo_cli server1.loc mod_dir_config dir_grpacct2_sid=''

Thanks! I wonder if the same bug is present in other functions as well. Did you check?

[alxgu]

Yes, this kind of value check is only in mod_dir_config

[seveas]

Great, thanks! I'll merge this later today and add a test for this.

Now cherry-picked, and test added.
