Wireguard fails to start when adding an IPv6 to AllowedIP.

Example Config:
[Interface]
PrivateKey = 0OpsgK/Wl7VJC2I49UiGL91wBlbqN+XP0R+bSH+VL2w=
MTU = 1200
Address = 10.0.0.5/24,fdb8:a70c:b109:9935::1/64

[Peer]
PublicKey = hk7hdCE2vKFu895RiCYhQTK6V9+zhnI+KI46VVSx1DA=
AllowedIPs = 10.0.0.1/24,fdb8:a70c:b109:9935::/64
Endpoint = 127.0.0.1:50300


Here's what happens when I try to start the config with wg-quick:

# wg-quick up wg1
[#] ip link add wg1 type wireguard
[#] wg setconf wg1 /dev/fd/63
[#] ip address add 10.0.0.5/24 dev wg1
[#] ip address add fdb8:a70c:b109:9935::1/64 dev wg1
[#] ip link set mtu 1200 up dev wg1
[#] ip route add fdb8:a70c:b109:9935::/64 dev wg1
RTNETLINK answers: No such device
[#] ip link delete dev wg1

I could reproduce this behaviour under ArchLinux and OpenSuse.

IPv6 cannot work with MTU less than 1280 on the device.
