From: Thinh Nguyen <Thinh.Nguyen@xxxxxxxxxxxx> commit d3abda5a98a18e524e17fd4085c9f4bd53e9ef53 upstream. Normally the END_TRANSFER command completion handler will clear the DWC3_EP_TRANSFER_STARTED flag. However, if the command was sent without interrupt on completion, then the flag will not be cleared. Make sure to clear the flag in this case.
