net/mlx5e: Update netdev features after changing XDP state

[ Upstream commit 2530297fc7c0df8739f3b5d2d6d3eaf5fab0695a ]

Some features (LRO, HW GRO) conflict with XDP. If there is an attempt to
enable such features while XDP is active, they will be set to `off
[requested on]`. In order to activate these features after XDP is turned
off, the driver needs to call netdev_update_features(). This commit adds
this missing call after XDP state changes.

Fixes: 2125deee1f60 ("net/mlx5e: Properly block HW GRO when XDP is enabled")
