net/mlx5e: Update netdev features after changing XDP state

Browse Source 
[ Upstream commit f6279f113ad593971999c877eb69dc3d36a75894 ]

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: cf6e34c8c22f ("net/mlx5e: Properly block LRO when XDP is enabled")
Fixes: b0617e7b3500 ("net/mlx5e: Properly block HW GRO when XDP is enabled")
