Honestly speaking I am not the best at debugfs core, but I still think
the link is connected to a struct debugfs node and not to any path..
This node is connected to a path though. And so even after rename
things should stay stable without your new step...
Just try and see if I am right or wrong.. Otherwise what you already
did is correct as you need to remove links for 2-3 as well..
