nat: avoid hairpinning infinite loop problem
Fix in nat44 hairpinning code to check if anything was actually changed in the snat_hairpinning() routine, and return 0 if nothing changed. This helps avoid an infinite loop repeating the three nodes nat44-hairpinning-->ip4-lookup-->ip4-local in case there was no change. Also add a corresponding test case.
