usb: dwc3: gadget: Avoid continuing preparing TRBs during teardown
Add checks similar to dwc3_gadget_ep_queue() before kicking off
transfers after getting an endpoint completion event. Since cleaning
up completed requests will momentarily unlock dwc->lock, there is a
chance for a sequence like pullup disable to be executed. This can
lead to preparing a TRB, which will be removed by the pullup disable
routine.
