Redfish(Ethernet): Send the correct JSON response after creating the IPV4 object.

Before this commit after creating the IPv4 address object,JSON response
was having empty string for the newly added object.

This commit fixes the problem.

Tested By:
Assuming there are already two IP addresses configured then the following
PATCH request would throw the following output

PATCH -D patch.txt -d '{"IPv4Addresses": [{},{},{"Address": "a.a.a.a","Address
Origin": "Static","SubnetMask": "255.255.0.0","Gateway":"g.g.g.g"}]}

{
  "@odata.id": "/redfish/v1/Managers/bmc/EthernetInterfaces/eth0",
  "HostName": "witherspoon",
  "IPv4Addresses": [
    {
      "Address": "169.254.201.17",
      "AddressOrigin": "IPv4LinkLocal",
      "Gateway": "9.3.185.1",
      "SubnetMask": "255.255.0.0"
    },
    {
      "Address": "9.3.185.83",
      "AddressOrigin": "Static",
      "Gateway": "9.3.185.1",
      "SubnetMask": "255.255.255.0"
    },
    {
      "Address": "a.a.a.a",
      "Gateway": "g.g.g.g",
      "SubnetMask": "255.255.0.0"
    }
  ],
