usb: gadget: f_sourcesink: Fix isoc transfer for USB_SPEED_SUPER_PLUS

mainline inclusion
from mainline-v5.17-rc2
commit 904edf8a
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4K4
CVE: CVE-2021-47270

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=904edf8aeb459697129be5fde847e2a502f41fd9



--------------------------------

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.
