RFR: 8320219: Actually resolve issues with goto labels in sspi [v3]

[Julian Waters]

> I regret not actually addressing the issues with the goto labels in https://github.com/openjdk/jdk/pull/15996, I've as such fixed the issues with them properly this time, by simply deleting the labels and duplicating the code where they're used. As mentioned, this unfortunately does increase duplicate code, but is the cleanest solution I could come up with for the labels

Julian Waters has updated the pull request incrementally with one additional commit since the last revision:

  NULL to nullptr in sspi.cpp
