Revert of Change SPACEPARITY in the Windows serial api implementation to ODDPARITY. (https://codereview.chromium.org/396023003/)

Reason for revert:
Very speculative revert for current XP bots failures (all 3 bots are failing with obscure errors and this is our last suspect in the list...).

I'll reland if that's not it.

Thanks for your understanding!
