Fix Service_ModeTranslation memory corruption
Jeffrey Lee authored 
In HandleServiceModeTranslation, make sure WsPtr is initialised
correctly before trying to use it. Fixes system heap corruption when
responding to Service_ModeTranslation (most likely overwriting part of
ChocolateMABlocks, and causing a crash when loading future modules)
