usb: dwc3: gadget: Improve dwc3_gadget_suspend() and dwc3_gadget_resu…
…me() commit c854087 upstream. Prevent -ETIMEDOUT error on .suspend(). e.g. If gadget driver is loaded and we are connected to a USB host, all transfers must be stopped before stopping the controller else we will not get a clean stop i.e. dwc3_gadget_run_stop() will take several seconds to complete and will return -ETIMEDOUT. Handle error cases properly in dwc3_gadget_suspend(). Simplify dwc3_gadget_resume() by using the introduced helper function.
