Merge branch 'ipv6-Change-addrconf_f6i_alloc-to-use-ip6_route_info_create'

David Ahern says:

====================
ipv6: Change addrconf_f6i_alloc to use ip6_route_info_create

addrconf_f6i_alloc is the last caller of fib6_info_alloc besides
ip6_route_info_create. There really is no good reason for it do
its own fib6_info initialization, so convert it to call
ip6_route_info_create.
