dsound: Set default primary buffer sample rate and bits per sample.

Programs that are written specifically for 2000 and xp don't bother to
set the primary buffer format because it's a noop.  However wine is
patterned after win9x and DirectX 7 or earlier which has a real
primary buffer and expects the program to change the primary buffer
format if necessary.
