New suggestion for overwriting a reference is wrong for mutable references

[cyrgani]

Code

fn change_val(mut val: &mut i32) {
    val = &mut 10;
}

Current output

warning: value assigned to `val` is never read
 --> src/lib.rs:2:5
  |
2 |     val = &mut 10;
  |     ^^^
  |
  = note: `#[warn(unused_assignments)]` on by default
help: you might have meant to mutate the pointed at value being passed in, instead of changing the reference in the local binding
  |
1 ~ fn change_val(val: &mut mut i32) {
2 ~     *val = 10;
  |

<other warning and error elided as they do not matter here>

Desired output

warning: value assigned to `val` is never read
 --> src/lib.rs:2:5
  |
2 |     val = &mut 10;
  |     ^^^
  |
  = note: `#[warn(unused_assignments)]` on by default
help: you might have meant to mutate the pointed at value being passed in, instead of changing the reference in the local binding
  |
1 ~ fn change_val(val: &mut i32) {
2 ~     *val = 10;
  |

<other warning and error elided as they do not matter here>
