xhci: handle USB_RET_NAK

Add a field to XHCITransfer to correctly keep track of NAK'ed usb
packets.  Retry transfers when the endpoint is kicked again.  Implement
wakeup_endpoint bus op so we can kick the endpoint when needed.

With this patch applied the emulated hid devices are working correctly
when hooked up to xhci.  usb-tabled without polling, yay!
