Rollup merge of #139626 - m-ou-se:mut, r=lqd

Remove unnecessary `mut` in test.

The value is moved in `pin!()`, so the binding doesn't need to be `mut` itself.

(Rustc doesn't warn about this due to the current hacky implementation of `pin!()`. That is fixed by https://github.com/rust-lang/rust/pull/139114.)
