dm: fix an 'undefined' error in some macros

Due to a non-existing parameter name in macro's, use of those macro's will
cause a compiler error of "undefined reference".
Unfortunately, dm test doesn't fail because a wrong name ("&dev", hence it
is accidentally a valid name in the context of a caller site) is passed on.
