netfilter: flowtable: fix nft_flow_route source address for nat case
For snat and dnat cases, the saddr should be taken from reverse tuple. Fixes: 3412e1641828 (netfilter: flowtable: nft_flow_route use more data for reverse route) Signed-off-by: wenxu <wenxu@chinatelecom.cn> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
