usb: dwc3: gadget: Ignore NoStream after End Transfer
The End Transfer command from a stream endpoint will generate a NoStream
event, and we should ignore it. Currently we set the flag
DWC3_EP_IGNORE_NEXT_NOSTREAM to track this prior to sending the command,
and it will be cleared on the next stream event. However, a stream event
may be generated before the End Transfer command completion and
prematurely clear the flag. Fix this by setting the flag on End Transfer
completion instead.
