[PATCH v2] usb-host: map LIBUSB_SPEED_SUPER_PLUS to USB_SPEED_SUPER |

Handle host superspeedplus (usb 3.1+) devices like superspeed (usb 3.0)
devices. That is enough to get them handled properly by xhci. They show
up as superspeed devices inside the guest, but should be able to actually
run at higher speeds.
