wifi-scripts: ucode: fix wifi-vlan "network" option not working

The call to netifd.set_vlan(...) had an incorrect argument
order. It should be (interface, ifname, vlan) not
(interface, vlan, ifname). This prevented wifi-vlan's
"network" option from working as netifd was not able
to find the wifi-vlan section.
