Now incorporate is fixed to copy across the properties we need in the superclass, we don't need to do the subclass ->probe(). Note, we still need to do the subclassed ->probe() when using FU_UDEV_DEVICE_FLAG_VENDOR_FROM_PARENT or when looking at properties on the parent device. This also removes the spurious 'already set GType to FuVliUsbhubDevice, ignoring FuVliUsbhubDevice' messages when running the daemon.
