During a USB cable disconnect, or soft disconnect scenario, a pending SETUP transaction may not be completed, leading to the following error:
dwc3 a600000.dwc3: timed out waiting for SETUP phaseIf this occurs, then the entire pullup disable routine is skipped and proper cleanup and halting of the controller does not complete.
Instead of returning an error (which is ignored from the UDC perspective), allow the pullup disable routine to continue, which will also handle disabling of EP0/1. This will end any active transfers as well. Ensure to clear any delayed_status also, as the timeout could happen within the STATUS stage.
