nat: prevent creation when-resolved static mappings on errors
When you create two identical NAT44 static mappings using interface name as external address and only local or ext port is different, VALUE_EXIST will be raised but when-resolved static mapping will remain. vpp# nat44 add static mapping tcp local 10.128.0.129 443 external GigabitEthernet0/8/0 8443 vpp# nat44 add static mapping tcp local 10.128.0.129 80 external GigabitEthernet0/8/0 8443 nat44 add static mapping: Mapping already exist. vpp# show nat44 static mappings NAT44 static mappings: tcp local 10.128.0.129:443 external 2.2.2.2:8443 vrf 0 tcp local 10.128.0.129:443 external GigabitEthernet0/8/0:8443 vrf -1 tcp local 10.128.0.129:80 external GigabitEthernet0/8/0:8443 vrf -1 With this commit, when-resolved static mapping is not created if the translation only differs in local or ext port.
