The various errors that are possible when processing a PQAP

convey that everything was fine.

Fix the check so that the guest can examine the condition code
to determine whether GPR1 has meaningful data.


Hey Eric, I have yet to see this produce a fail in my AP KVM unit tests.
If you find some spare time I'd like to discuss how I can extend my test so that I can see the fail before it's fixed.
