netfilter: nft_flow_offload: Fix reverse route lookup
Using the following example:
client 1.1.1.7 ---> 2.2.2.7 which dnat to 10.0.0.7 server
The first reply packet (ie. syn+ack) uses an incorrect destination
address for the reverse route lookup since it uses:
daddr = ct->tuplehash[!dir].tuple.dst.u3.ip;
which is 2.2.2.7 in the scenario that is described above, while this
should be:
daddr = ct->tuplehash[dir].tuple.src.u3.ip;
that is 10.0.0.7.
