libata: kill ATA_HORKAGE_DMA_RW_ONLY
ATA_HORKAGE_DMA_RW_ONLY for TORiSAN is verified to be subset of using DMA for ATAPI commands which aren't aligned to 16 bytes. As libata now doesn't use DMA for unaligned ATAPI commands, the horkage is redundant. Kill it. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
