RFR: 8301457: Code in SendPortZero.java is uncommented even after JDK-8236852 was fixed [v2]

[Michael McMahon]

> Hi,
> 
> JDK-8236852 was fixed in 15 and included its own regression test, but a couple of existing tests have code commented out that also test this functionality. One scenario relating to sending to the wildcard address was not addressed and remains commented out.

> Thanks,
