ipv6: fix IPv6 processing of sessions that only have only a link-local address
Several modules assume that if ses->ipv6 is set, then
ses->ipv6->addr_list contains at least one element. But this is not
true if ipv6 was allocated by the pseudo ipdb backend of ipv6cp
(ipv6cp_opt_intfid.c). That is, if the PPP session only has an
automatic link-local address.
This leads modules like pppd-compat and dhcpv6 to access invalid memory
when trying to retrieve the IPv6 address of a PPP session.
