Check `dyn*` return type correctly In `check_fn`, if the declared return type is `dyn Trait`, then we check the return type separately to produce better diagnostics, because this is never valid -- however, when `dyn*` was introduced, this check was never adjusted to only account for *unsized* `dyn Trait` and not *sized* `dyn* Trait`. Fixes rust-lang#104501
