net/mlx5e: Fix IPsec tunnel mode offload feature check
[ Upstream commit 9a52f6d44f4521773b4699b4ed34b8e21d5a175c ]
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).
