Description

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: Skip restore TC rules for vport rep without loaded flag

During driver unload, unregister_netdev is called after unloading
vport rep. So, the mlx5e_rep_priv is already freed while trying to get
rpriv->netdev, or walk rpriv->tc_ht, which results in use-after-free.
So add the checking to make sure access the data of vport rep which is
still loaded.
