[net-next 01/13] net/mlx5e: Print a warning when LRO feature is dropped or not allowed

[Saeed Mahameed]

From: Huy Nguyen <h...@mellanox.com>

When user enables LRO via ethtool and if the RQ mode is legacy,
mlx5e_fix_features drops the request without any explanation.
Add netdev_warn to cover this case.

Fixes: 6c3a823e1e9c ("net/mlx5e: RX, Remove HW LRO support in legacy RQ")
