Subject: [PATCH] [net-next, netfilter] mlx5: avoid unused variable warning

Without CONFIG_MLX5_ESWITCH we get a harmless warning:

drivers/net/ethernet/mellanox/mlx5/core/en_main.c:3467:21: error: unused variable 'priv' [-Werror,-Wunused-variable]
        struct mlx5e_priv *priv = netdev_priv(dev);

Hide the declaration in the same #ifdef as its usage.

Fixes: 4e95bc268b91 ("net: flow_offload: add flow_block_cb_setup_simple()")
