Subject: net/mlx5e: Disable netdev after close

From: Saeed Mahameed <saeedm@mellanox.com>


[ Upstream commit 37f304d10030bb425c19099e7b955d9c3ec4cba3 ]

Disable netdev should come after it was closed, although no harm of doing it
before -hence the MLX5E_STATE_DESTROYING bit- but it is more natural this way.
