[PATCH mlx5-next 12/17] net/mlx5: Don't advertise IPsec netdev support for non-IPsec device

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@nvidia.com>

Device that lacks proper IPsec capabilities won't pass mlx5e_ipsec_init()
later, so no need to advertise HW netdev offload support for something that
isn't going to work anyway.

Fixes: 8ad893e516a7 ("net/mlx5e: Remove dependency in IPsec initialization flows")
