Currently when gadget enumerates in super speed plus, the isoc endpoint request buffer size is not calculated correctly. Fix this by checking the gadget speed against USB_SPEED_SUPER_PLUS and update the request buffer size. Fixes: 90c4d05780d4 ("usb: fix various gadgets null ptr deref on 10gbps cabling.")
