net/mlx5e: Update netdev features after changing XDP state

stable inclusion

commit e9fe72b95d7f538a956dbe7455e81dc5ebbfb0e6
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5W6OE

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e9fe72b95d7f538a956dbe7455e81dc5ebbfb0e6

--------------------------------

[ Upstream commit f6279f11 ]

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: cf6e34c8 ("net/mlx5e: Properly block LRO when XDP is enabled")
Fixes: b0617e7b ("net/mlx5e: Properly block HW GRO when XDP is enabled")
