    linuxkpi: Update `struct irq_work`
    
    The previous `llnode` field is moved inside another field `node`.
    
    This `node` field is a `struct __call_single_node` in Linux. Here, we
    simply add an anonymous struct with the `llnode` field inside. That
    field's new name is `llist` now.
    
    V2: Use an anonymous union to keep the structure backward compatible
        with drivers using the previous `llnode` field. This was suggested
        by wufl@ and hselasky@. Thank you!
