Windows: Fix mythread_once() macro with Vista threads.

Don't call InitOnceComplete() if initialization was already done.

So far mythread_once() has been needed only when building
with --enable-small. windows/build.bash does this together
with --disable-threads so the Vista-specific mythread_once()
is never needed by those builds. VS project files or
CMake-builds don't support HAVE_SMALL builds at all.
