Disable assertion in idSampleDecoderLocal::Decode*(), fix #461

Browse source 
It happened a lot more since
  504b572a Update sounds at ~60Hz instead of ~10Hz, fixes #141
(because then MixLoop() is more likely to be called in the narrow
 timeframe this can happen during level load) but could happen before.
So far I only observed it when starting a new game in Classic Doom 3.
See comment in the change and #461 for more information.
