make "directive in macro's argument list" a warning
The presence of preprocessor directives within the arguments
of a macro invocation is Undefined Behaviour [6.10.3p11].
Sparse issues an error for this but most often the result is
well defined and is not a problem, processing can continue
(for example, when the directive is one of the conditional ones).
So, downgrade this sparse_error() to warning() (especially
because issuing an error message can hide those coming later).
