usb: dwc_otg_310: gadget: stop current transfer on dequeue

If the request being dequeued is already started, disable endpoint
to stop the transfer and then call dwc_otg_request_done().
Endpoint will be re-enabled on next call to dwc_otg_ep_start_transfer().

TEST=use RK3128/RK3288/RK3368 board, adb root and then adb reboot,
check if usb_req->buf is used after free.
