[PATCH] net/mlx5e: Move priv variable into case statement in mlx5e_setup_tc

[Nathan Chancellor]

There is an unused variable warning on arm64 defconfig when
CONFIG_MLX5_ESWITCH is unset:

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

Move it down into the case statement where it is used.

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