vif: T3349: use fixed ordering when enabling parent and child interface
When a VIF/VLAN interface is placed in admin down state but the lower
interface, serving the vlan, is moved from admin down -> admin up, all its
vlan interfaces will be placed in admin up state, too.
This is bad as a VLAN interface will become admin up even if its specified as
admin down after a reboot.
To reproduce:
set interfaces ethernet eth1 vif 20 disable
set interfaces ethernet eth1 disable
commit
delete interfaces ethernet eth1 disable
commit
Now check the interface state and it returns UP,LOWER_UP
7: eth1.20@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
