[DSOUND #1] rename secondary buffer variable to secondary

[Robert Reif]

Change secondary buffer variable name to secondary.
Fix AddRef and Release to use proper class.

The second one is a bug fix but the memory layout of the two
classes are the same so the generated code turns out to be the same.

This is the first of a series of patches that breaks up my previous
DirectSoundFullDuplex patch into digestible pieces.
