net/mlx5e: advertise MACsec offload only when supported

Commit 339ccec8d43d ("net/mlx5: Enable MACsec offload feature for VLAN
interface") added NETIF_F_HW_MACSEC unconditionally to vlan_features so
that VLAN devices could inherit MACsec offload support.

mlx5e_build_nic_netdev subsequently copies vlan_features into
hw_features and features. As a result, all mlx5e NIC netdevices
advertise MACsec hardware offload, even when the firmware does not
support it and the driver does not install macsec_ops.

Set the MACsec feature bits in mlx5e_macsec_build_netdev, after device
capabilities have been validated. This preserves MACsec-over-VLAN
support and the ethtool feature control on capable devices, without
advertising either on unsupported hardware.
