Remove excess rib while resolving closures

I've mentioned this on [zulip](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/.60ClosureOrAsyncRibKind.60.20weirdness/near/286982959), in `rustc_resolve`, while resolving closures we add an excess `ClosureOrAsyncRibKind`. It's excess because we later add another one in `visit_fn`.

I couldn't find a way in which removing this will break anything, all test seem to pass, etc.
