Don't claim the API failed when it succeeded, and show the unexpected data.

kernel32/tests: On Windows 8 IdnToNameprepUnicode() returns a different error for invalid parameters.

Windows 8 and 8.1 return some different error codes and
GetDllDirectory() handles buffer termination a bit differently.

0x00333333 makes much more sense than 0x00000000, and is what most of my
hardware returns. Apparently at least some GF7 cards (still) return
0x00000000, so also accept that as broken().
