When creating links from a subdev to a sink, the current logic tries to
iterate over the endpoints of dev's fwnode.
This might not be correct when the subdev uses a different fwnode
compared to the dev's fwnode.
If, when registering, the subdev's fwnode is not set, the code inside
v4l2_async_register_subdev will set it to the dev's fwnode.
To fix this, just use the subdev's fwnode.
