vlan: Change vlan_dev_set_vlan_flag() to handle multiple flags at once
Change vlan_dev_set_vlan_flag() to handle multiple flags at once and rename to vlan_dev_change_flags(). This allows to to use it from the netlink interface, which in turn allows to handle necessary adjustments when changing flags centrally.
