usb: implement XHCI underrun/overrun events
Implement underrun/overrun events of isochronous endpoints according to XHCI spec (4.10.3.1) Guest software restarts data streaming when receives these events. The XHCI reports these events using interrupter assigned to the slot (as these events do not have TRB), so current commit adds the field of assigned interrupter to the XHCISlot structure. Guest software assigns interrupter to the slot on 'Address Device' and 'Evaluate Context' commands.
