Drew Hamilton 231bf7e839 usb: musb: fix gadget state on disconnect ...

commit 67a59f8219 upstream.

When unplugging the USB cable or disconnecting a gadget in usb peripheral mode with
echo "" > /sys/kernel/config/usb_gadget/<your_gadget>/UDC,
/sys/class/udc/musb-hdrc.0/state does not change from USB_STATE_CONFIGURED.

Testing on dwc2/3 shows they both update the state to USB_STATE_NOTATTACHED.

Add calls to usb_gadget_set_state in musb_g_disconnect and musb_gadget_stop
to fix both cases.
