libata: set dma_mode to 0xff in reset
commit 5416912af75de9cba5d1c75b99a7888b0bbbd2fb upstream.
ata_device->dma_mode's initial value is zero, which is not a valid dma
mode, but ata_dma_enabled will return true for this value. This patch
sets dma_mode to 0xff in reset function, so that ata_dma_enabled will
not return true for this case, or it will cause problem for pata_acpi.
