[PATCH v11 08/65] dyndbg: make ddebug_class_param union members same size

[Jim Cromie <jim.cromie@gmail.com>]

struct ddebug_class_param keeps a ref to the state-storage of the
param; make both class-types use the same unsigned long storage type.

ISTM this is simpler and safer; it avoids an irrelevant difference,
and if 2 users somehow get class-type mixed up (or refer to the wrong
union member), at least they will both see the same value.
