[IPSEC]: Move flow construction into xfrm_dst_lookup
This patch moves the flow construction from the callers of
xfrm_dst_lookup into that function. It also changes xfrm_dst_lookup
so that it takes an xfrm state as its argument instead of explicit
addresses.
This removes any address-specific logic from the callers of
xfrm_dst_lookup which is needed to correctly support inter-family
transforms.
