Do not send interface DOWN when deleting VPP int
Do not send interface DOWN when deleting VPP int

When deleting VPP interface (specifically afpacket) when interface
state DOWN is sent before deletion, it will set connected veth interface
to DOWN too. To prevent this and revert to behaviour before creation of
afpacket, do not send DOWN and just delete the interface.
