Subject: net/mlx5e: Print a warning when LRO feature is dropped or not allowed
Patch-mainline: v5.4-rc1
Git-commit: 842a2eb28f14b184c7a653448f402f5273e6ff5c
References: bsc#1103990 FATE#326006

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")
