The err.span_suggestion statement above has made some modifications to err, I guess that might be the reason why we should return true here as well?

…bank suggest type annotation for local statement initialed by ref expression In a local statement with a type declaration, if a ref expression is used on the right side and not used on the left side, in addition to removing the `&` and `&mut` on the right side, we can add them on the left side alternatively Fixes rust-lang#102892
