Title
net/mlx5: Unregister devlink params in case interface is down
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Unregister devlink params in case interface is down
Currently, in case an interface is down, mlx5 driver doesn't
unregister its devlink params, which leads to this WARN[1].
Fix it by unregistering devlink params in that case as well.
