Fix issue 15922: DMD segfault in functionParameters on invalid code

`Dsymbol.errors` is used to indicate a symbol failed semantic analysis.
Currently, `FuncDeclaration.semantic3` fails if the parent has error,
so the body of aggregates that already have errors is not processed.
However, the code was only `return`ing and not setting `Dsymbol.errors`
to `true`, resulting in this error being unnoticed by `functionSemantic`.
