devusb: superspeed bandwidth allocation handled by controller, skip usbload() calculation
with xhci, bandwidth allocations are handled by the controller
and there are various speed settings possible that currently
not exposed in the Udev. so just keep usbload() as it is for
usb2 and keep ep->load as zero for superspeed.
