ip17xx: Maintain state->remove_tag incrementally
So far, state->remove_tag was sometimes updated incrementally, sometimes left to correct_vlan_state() to recalculate. Since I want to avoid use of correct_vlan_state() for IP175D, this patch fixes the only two remaining places which leave state->remove_tag inconsistent with state->add_tag and it drops the recalculation.
