usb: gadget: f_sourcesink: Fix isoc transfer for USB_SPEED_SUPER_PLUS
commit 904edf8aeb459697129be5fde847e2a502f41fd9 upstream.
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.")
