usb: gadget: udc: renesas_usb3: fix oops in renesas_usb3_remove()
commit e3190868e5f52fb26544f16463593d54ce46ce61 upstream.
This patch fixes an issue that the renesas_usb3_remove() causes
NULL pointer dereference because the usb3_to_dev() macro will use
the gadget instance and it will be deleted before.
Fixes: cf06df3fae28 ("usb: gadget: udc: renesas_usb3: move pm_runtime_{en,dis}able()")
