USB: fix formatting of SuperSpeed endpoints in /proc/bus/usb/devices

Isochronous and interrupt SuperSpeed endpoints use the same mechanisms
for decoding bInterval values as HighSpeed ones so adjust the code
accordingly.

Also bandwidth reservation for SuperSpeed matches highspeed, not
low/full speed.
