usb: gadget: f_sourcesink: Fix isoc transfer for USB_SPEED_SUPER_PLUS
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.")
