net/ipv6: reserve room for IFLA_INET6_ADDR_GEN_MODE
inet6_ifla6_size() is called to check how much space is needed by
inet6_fill_link_af() and inet6_fill_ifinfo(), both of which include
the IFLA_INET6_ADDR_GEN_MODE attribute. Reserve some room for it.
Fixes: bc91b0f07ada ("ipv6: addrconf: implement address generation modes")
