Fix issue 18232: local vars in union member functions needs initializer.

The `isunion` condition is too broad, because it also excludes local
variables declared inside union member functions. Moreoever, it is not
necessary, because the `fd` condition later on already excludes union
fields, since they would not be inside a function declaration.
