Christoph Hellwig dff8d6c1ed swiotlb: remove the overflow buffer 
Like all other dma mapping drivers just return an error code instead
of an actual memory buffer.  The reason for the overflow buffer was
that at the time swiotlb was invented there was no way to check for
dma mapping errors, but this has long been fixed.
