usb: renesas_usbhs: gadget: usbhsg_ep_disable() care pipe settings
Current usbhsg_ep_disable() didn't care uep->pipe and pipe->mod_private variable which is used on usbhsg_ep_enable(). It breaks renesas_usbhs gadget when resume. This patch fixes it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
