dhcpv6-ia: fix logic to include IA_PD prefix with lifetimes set to 0
Make sure IA_PD prefixes for which no preferred and valid lifetimes
can be returned are included in the reply with a preferred and valid
lifetime to 0.
Therefore exclude IPv6 prefixes with an invalid prefix length as
well so IA_PD prefixes for which not a preferred/valid lifetime is
returned are included with a preferred and valid lifetime set to 0
