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.
