Fix missed CheckArguments on ndparams for SetNodeParams

In the previous patch where I modified LUSetNodeParams to take ndparams
into account I missed this additional check of parameters in the Logical
Unit. This patch adds ndparams to the recognized parameter lists which
has to be filled out if nothing else is.
