usb: renesas_usbhs: gadget: Do not discard queues in usb_ep_set_{halt,wedge}()
The commit 97664a207bc2 ("usb: renesas_usbhs: shrink spin lock area") had added a usbhsg_pipe_disable() calling into __usbhsg_ep_set_halt_wedge() accidentally. But, this driver should not call the usbhsg_pipe_disable() because the function discards all queues. So, this patch removes it.
