[libata] fix bugs in ATAPI padding DMA mapping code The ATAPI pad-to-next-32bit-boundary code modifies the scatterlist's length variable, sometimes to zero. x86-64 platform would oops if a zero-length scatterlist entry was asked to be mapped. Work around this by ensuring that we never DMA-map a zero length buffer or SG entry.
