drivers/net, ipv6: Select IPv6 fragment idents for virtio UFO packets

Browse Source 
UFO is now disabled on all drivers that work with virtio net headers,
but userland may try to send UFO/IPv6 packets anyway.  Instead of
sending with ID=0, we should select identifiers on their behalf (as we
used to).
