net/mlx5e: Update features on ring size change

Browse Source 
When the ring size 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
$ ethtool --set-ring eth1 rx 1024

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