net: Fix vlan_features propagation
Fix VLAN features propagation for devices which change vlan_features.
For this to work, driver needs to make sure netdev_features_changed()
gets called after the change (it is e.g. after ndo_set_features()).
Side effect is that a user might request features that will never
be enabled on a VLAN device.
