MLK-21243 usb: dwc3: gadget: check if dep->frame_number is still valid
This is a porting patch from upstream commit d53701067f04
("usb: dwc3: gadget: check if dep->frame_number is still valid")
Gadget driver may take an unbounded amount of time to queue requests
after XferNotReady. This is important for isochronous endpoints which
need to be started for a specific (micro-)frame.
If we fail to start a transfer for isochronous endpoint, let's try
queueing to a future interval and see if that helps. We will stop trying
if we fail a start transfer for 5 intervals in the future.
