Fix shadow_same's positive false for async function's params:
Example Code:
```rust
#![deny(clippy::shadow_same)]
pub async fn foo(_a: i32) {
}
```
Output:
```
error: `_a` is shadowed by itself in `_a
```
Hir:
```rust
pub async fn foo(_a: i32)
->
/*impl Trait*/ #[lang = "from_generator"](move |mut _task_context|
{
let _a = _a;
{ let _t = { }; _t }
})
```
Skip checking async function's params.
