Linyu Yuan 40edb52298 usb: dwc3: avoid NULL access of usb_gadget_driver 
we found crash in dwc3_disconnect_gadget(),
it is because dwc->gadget_driver become NULL before async access.
7dc0c55e9f ('USB: UDC core: Add udc_async_callbacks gadget op')
suggest a common way to avoid such kind of issue.

this change implment the callback in dwc3 and
change related functions which have callback to usb gadget driver.
