This uses the dma safe check for REQ_TYPE_ATA_PC. The dma safe check
is used for only sg requests but it should be used for other non fs
commands.
This uses blk_queue_update_dma_pad to make the intention clear though
ide don't use the blk APIs so it doesn't change anything.

Some REQ_TYPE_ATA_PC commands uses the stack buffers for DMA, which
leads to memory corruption on a non-coherent platform.
With regard to alignment and padding, ide-cd has the the dma safe
check for sg requests and REQ_TYPE_ATA_PC. This adds the stack buffer
check to that check.
