[PATCH nft] statement: Print NAT IPv4 address in nat_stmt_print()

[Elise Lennion <elise.lennion@xxxxxxxxx>]

The case which "nat.addr != NULL && nat.proto != NULL && type != ipv6"
wasn't caught in nat_stmt_print(). Now all cases should be considered.

Also, the if statements were reorganized to get rid of one nested if.

Fixes(Bug 1117 - Table ipv4-nat prerouting dnat doesn't accept dest IP:PORT)
