Subject: [net-next 15/15] net/mlx5e: Remove the duplicating check for striding RQ when enabling LRO

From: Maxim Mikityanskiy <maximmi@...dia.com>

LRO requires striding RQ and checks that it's enabled at two places:
mlx5e_fix_features and set_feature_lro. This commit keeps only one check
at mlx5e_fix_features and removes the duplicating one in
set_feature_lro.
