Redfish(Network): Support for deletion of IP address through PATCH operation

Before this commit we were reading the IPV4address through readJSON
function in vector of json, readJSON doesn't like the null list
parameter and throws the error as below

"The value null for the property IPv4Addresses is of a different type
than the property can accept"

This commit fixes that problem and some restructuring the code to make
delete work.

TestedBy:
PATCH {"IPv4Addresses": [{},null,{},{}]}
   deletes second object
PATCH {"IPv4Addresses": [null,{}]}
   deletes first object

Suppose if the IPv4Address has two addresses then the
Following PATCH request would give the folowing error.

PATCH {"IPv4Addresses": [{},{},null]
{
  "IPv4Addresses/0@Message.ExtendedInfo": [
    {
      "@odata.type": "/redfish/v1/$metadata#Message.v1_0_0.Message",
      "Message": "The value [{},{},null] for the property IPv4Addresses/2 is of a
                  different format than the property can accept.",
      "MessageArgs": [
        "[{},{},null]",
        "IPv4Addresses/2"
      ],
}
