[net-next 03/12] net/mlx5e: TC ipv4 tunnel encap offload cosmetic changes

[Saeed Mahameed <saeedm@mellanox.com>]

From: Or Gerlitz <ogerlitz@mellanox.com>

Move around some settings of variables as pre-step to make things
more robust and clear for the ipv6 case in down-stream patch.
This patch doesn't change any functionality.
