Fix 2021 `dyn` suggestion that used code as label

The arguments to `span_suggestion` were in the wrong order, so the error
looked like this:

    error[E0783]: trait objects without an explicit `dyn` are deprecated
      --> src/test/ui/editions/dyn-trait-sugg-2021.rs:10:5
       |
    10 |     Foo::hi(123);
       |     ^^^ help: <dyn Foo>: `use `dyn``

Now the error looks like this, as expected:

    error[E0783]: trait objects without an explicit `dyn` are deprecated
      --> src/test/ui/editions/dyn-trait-sugg-2021.rs:10:5
       |
    10 |     Foo::hi(123);
       |     ^^^ help: use `dyn`: `<dyn Foo>`

This issue was only present in the 2021 error; the 2018 lint was
correct.
