wmaker: removed case from switch that is unreachable (Coverity #50043)

There is a check a few line above that already return from the function
because there is nothing to do for that case, so the case statement cannot
be reached. As not all case are covered in that switch anyway that won't
make a difference, and because an 'int' is used instead of an 'enum' the
compiler will not be able complain anyway.
