net/mlx5e: Fix IPsec tunnel mode offload feature check
Remove faulty check disabling checksum offload and GSO for offload of
simple IPsec tunnel L4 traffic. Comment previously describing the deleted
code incorrectly claimed the check prevented double tunnel (or three layers
of ip headers).
Fixes: f1267798c980 ("net/mlx5: Fix checksum issue of VXLAN and IPsec crypto offload")
