libpayload: Use interrupt transfers for USB hubs
In interactive payloads, the USB stack's poll procedure is implicitly called from the UI loop. Since all USB control transfers are handled synchronously, polling hubs with these slows the UI significantly down.
So switch to interrupt transfers that are done asynchronously and only perform control transfers when the hub reported a status change.
