bug
**What is the current behavior?**
React hooks linter fails with this piece of code

```js
function useHook() {
  const ref = React.useRef([1, 2, 3]);
  const res = []
  // valid because there are not unexpected returns
  if (ref.current) {
    for (let i = 0; i !== ref.current.length && !ref.current[i]; ++i ) {
      res.push(ref.current[i]);
    }
  }
  React.useLayoutEffect(() => {});
}
```

however a bit more usual for loop is handled as expected
```js
function useHook() {
  const ref = React.useRef([1, 2, 3]);
  const res = []
  if (ref.current) {
    for (let i = 0; i !== ref.current.length; ++i ) {
      res.push(ref.current[i]);
    }
  }
  React.useLayoutEffect(() => {});
}
```

**What is the expected behavior?**

Skip for looks without returns
