[KERNEL32]

- Make BaseSetLastNTError return the converted Win32 error code. This will determine the upper 24 bits of EAX in functions that return BOOLEAN FALSE right after calling BaseSetLastNTError, e.g. Wow64EnableWow64FsRedirection. Fixes installers using WiX Toolset (e.g. VS2012 redist) on MSVC builds.
See http://wixtoolset.org/issues/4681/ for the WiX bug that causes this.
