Parse failure for `await set()` - cannot use "await" as identifier inside an async function

```js
import { parseModule } from "meriyah";

let code = `
let foo = async () => {
    bar();
    await set();
};
`;

const result = parseModule(code);
console.log(result);
```

If I remove the call to `bar()`, or rename `set()` to something else (e.g. `setFn()`), it parses without error.

`meriyah@6.0.5`.
