Very small but very COOL fix.
This commit fixed the Hang-up in many games, like "New Super Mario Bros. Wii", "Resident Evil: The Darkside Chronicles", "Fatal Frame 4: Tsukihami no Kamen", "Muramasa: The Demon Blade", and etc. You name it. OH YEAH! This little issue really cost me some *serious* debugging time, phew... git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@4616 8ced0084-cf51-0410-be5f-012b33b47a6e
