Disable broken idSIMD_SSE::UpSampleOGGTo44kHz()

It corrupted the stack when called with buffers allocated on the stack
and numSamples that are not a multiple of four, apparently, by writing
4 floats too many, at least in the 22KHz Stereo case..

This caused the crash described in
  dhewm/dhewm3#303 (comment)

Now it just uses the generic C code, like all platforms besides MSVC/x86
already do.
