move recommendation with closure and invalid lifetime is inserted at the wrong place

[sosthene-nitrokey]

Code

#[derive(Default)]
struct A {}

struct B<'a> {
    a: &'a mut A,
}

struct C<'a, 'b> {
    b: &'b mut B<'a>,
}

fn some_fn<'a>(b: &mut B<'a>, f: impl FnOnce(&C<'a, '_>)) {}

fn main() {
    let some_closure = |_fs| {};

    for _ in [1] {
        let mut a = Default::default();
        let mut b = B { a: &mut a };
        some_fn(&mut b, |c| {
            some_closure(c);
        });
    }
}

Current output

error[E0373]: closure may outlive the current block, but it borrows `a`, which is owned by the current block

note: block requires argument type to outlive `'1`

   |             ^^^^^^^^^^^^
help: to force the closure to take ownership of `a` (and any other referenced variables), use the `move` keyword
   |
19 |         let mut b = B { a: move &mut a };
   |                            ++++

Desired output

move should not be recommended as it does not solve any issue. This is the case even if put at the closure definition since the closure does not capture anything.

Rationale and extra context

The recommendation for the move is wrong.

Other cases

No response

Anything else?
