net: cpsw_new: unregister devlink on port registration failure

cpsw_probe() registers devlink before registering the CPSW ports.

If cpsw_register_ports() fails, the error path only unregisters the
notifiers and then releases the lower level resources. It does not undo
the successful cpsw_register_devlink() call, leaving the devlink instance
and its parameters registered after probe has failed.

Add a devlink cleanup label for the path where devlink registration has
already succeeded, and use it when port registration fails.
