Remove unnecessary `clone` from `needless_collect` example

The example for [clippy::needless_collect](https://rust-lang.github.io/rust-clippy/master/#needless_collect) is written as follows:

```rust
let len = iterator.clone().collect::<Vec<_>>().len();
// should be
let len = iterator.count();
```

With this change, the unnecessary `clone()` is removed and the the standard

    ### Example
    ```rust
    // original
    ```
    Use instead:
    ```rust
    // improved
    ```

structure is followed.
