Fix config requirements of IPv6

[PATCH] Fix config requirements of IPv6

net/ipv6/inet6_connection_sock.c in function __inet6_csk_dst_store() requires flow_cache_genid which is defined in net/core/flow.c which is compiled when CONFIG_XFRM is set.

This patch expresses that dependency.

IPV6 should not require XFRM, a proper fix for this issue was added to the net-2.6.24 tree earlier today already.
