[WINEOSS] use default prepare functions

[Robert Reif]

Fall back to default header prepare and unprepare functions.

A driver only needs to support prepare and unprepare functions
when it is doing something special like allocating a DMA buffer for
each header.  Since we don't do anything special, just fall back
to the default functions.  Removes redundant code.
