Revert "veth: T3829: Allow moving veth into netns"

netns management for any Vyos interfaces doesn't work past the initial
creation, because Vyos always tries to recreate it/move it into the
netns even though it already exists. Until this is fixed, don't let
anyone even attempt to use this:

    set interfaces virtual-ethernet veth10 peer-name 'veth100'
    set interfaces virtual-ethernet veth100 netns 'ns01'
    set interfaces virtual-ethernet veth100 peer-name 'veth10'
    set netns name ns01
    commit

    vyos@r14# sudo ip netns exec ns01 ip link show
    1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN mode DEFAULT group default qlen 1000
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    12: veth100@if13: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
