Subject: net/mlx5: Don't advertise IPsec netdev support for non-IPsec device
Patch-mainline: v5.19-rc1
Git-commit: a8444b0bdd1ae9c437fe6d3ef44f1ba4721c4329
References: jsc#PED-1549
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")
