ata: libata-eh: Do not use ATAPI DMA for a device limited to PIO mode

[ Upstream commit 91ec84f8eaddbc93d7c62e363d68aeb7b89879c7 ]

atapi_eh_request_sense() currently uses ATAPI DMA if the SATA controller
has ATA_FLAG_PIO_DMA (PIO cmds via DMA) set.

However, ATA_FLAG_PIO_DMA is a flag that can be set by a low-level driver
on a port at initialization time, before any devices are scanned.

If a controller detects a connected device that only supports PIO, we set
the flag ATA_DFLAG_PIO.

Modify atapi_eh_request_sense() to not use ATAPI DMA if the connected
device only supports PIO.
