usb: dwc3: gadget: Clear started flag for non-IOC

Browse Source 
commit d3abda5a98 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.
