net/mlx5e: Fix IPv6 tunnel checksum offload

The mlx5 driver exposes support for TSO6 but not IPv6 csum for hardware encapsulated tunnels. This leads to issues as it triggers warnings in skb_checksum_help as it ends up being called as we report supporting the segmentation but not the checksumming for IPv6 frames. This patch corrects that and drops 2 features that don't actually need to be supported in hw_enc_features since they are Rx features and don't actually impact anything by being present in hw_enc_features.
