usb: dwc3: gadget: Submit endxfer command if delayed during disconnect

[ Upstream commit 8422b769

 ]

During a cable disconnect sequence, if ep0state is not in the SETUP phase,
then nothing will trigger any pending end transfer commands.  Force
stopping of any pending SETUP transaction, and move back to the SETUP
phase.
