Subject: [RFC PATCH 11/17] dyndbg-API: DYNDBG_CLASSMAP_USE drop extra args
Drop macro args after _var. Since DYNDBG_CLASSMAP_USE no longer
forwards to DYNDBG_CLASSMAP_DEFINE, it doesn't need those args to
forward. Keep only the _var arg, which is the extern'd struct
classmap with all the class info.
