ospf6d: fix iface commands lost when removing from area

In OSPFv3 when removing the interface from an area, all ospf6
interface commands are lost, so when changing the area you need
to reconfigure all ospf6 interface commands again

  r1# sh run
  interface r1-r2-eth0
   ipv6 address 2013:12::1/64
   ipv6 ospf6 dead-interval 4
   ipv6 ospf6 hello-interval 1
   ipv6 ospf6 network point-to-point
  !
  router ospf6
   ospf6 router-id 1.1.1.1
   interface r1-r2-eth0 area 0.0.0.0
  !

  r1# conf t
  r1(config)# router ospf6
  r1(config-ospf6)# no interface r1-r2-eth0 area 0.0.0.0
  r1(config-ospf6)# exit

  r1# sh run
  interface r1-r2-eth0
   ipv6 address 2013:12::1/64
  !                            <----- missing all ipv6 ospf6 commands
  router ospf6
   ospf6 router-id 1.1.1.1
  !

This is because the interface is being deleted instead of disabled
(see PR#7717) I believe the interface should be left as disabled
(not deleted) when removing the interface from the area
