usb: clamp bInterval to allowed range bInterval must be within the range 1 - 16 when running at High/Super speed, and within the range 1 - 255 when running at Full/Low speed. In order to catch drivers passing a too large bInterval on Super/High speed scenarios (thus overflowing urb->interval), let's clamp() the argument to the allowed ranges.
