Fix own stupid error in yesterday's refactor of recursive dir creation.

Missed adding return value in one place.

Thanks a lot to Thomas Szepe for reporting the issue and finding the solution!

Question remains: how could MSVC allow such a code to compile in some cases
(own win64 + scons buildbot win32 were OK with that it seems!).
Crappy compiler, not comming to the rescue of stupid dev...
