media: v4l2-fwnode: Check subdev count after checking port

Browse source

Current implementation of __v4l2_async_notifier_parse_fwnode_endpoints()
checks first whether subdev_count >= subdev_max and only then whether
the port being parsed matches the given port index. This triggers an
error in otherwise valid cases of skipping ports that do not match.

Fix this by moving the check below the port index check.

Fixes: 9ca4653121 ("media: v4l: fwnode: Support generic parsing of graph endpoints in a device")
