net/mlx5e: Update features on MTU change

Browse source

When the MTU changes successfully, trigger netdev_update_features() to
enable features in wanted state if applicable.

An example of such scenario:
$ ip link set dev eth1 up
$ ethtool --set-ring eth1 rx 8192
$ ip link set dev eth1 mtu 9000
$ ethtool --features eth1 rx-gro-hw on --> fails
$ ip link set dev eth1 mtu 7000

With this patch, HW GRO will be turned on automatically because
it is set in the device's wanted_features.
