driver core: Allow device_move(dev, NULL).
If we allow NULL as the new parent in device_move(), we need to make sure that the device is placed into the same place as it would if it was newly registered: - Consider the device virtual tree. In order to be able to reuse code, setup_parent() has been tweaked a bit. - kobject_move() can fall back to the kset's kobject. - sysfs_move_dir() uses the sysfs root dir as fallback.
