[PATCH v3] rust: workqueue: fix SAFETY comment incorrectly referencing `Arc`

[Sagar Taunk]

The `WorkItemPointer` implementation for `Pin<KBox<T>>` incorrectly
references `Arc::into_raw` when `KBox::into_raw` has been used.

Fixes: 47f0dbe8fdc2 ("rust: workqueue: implement `WorkItemPointer` for pointer types")

I originally sent this patch in April but it was not merged because I messed up on 
the tags. I remembered that I failed to follow up on this while trying to read this module.
