Log Message:
disable downgrade of ATA mode from DMA, as generally not relevant
any more - while it has been instrumental to inadvertedly discover
driver bugs in PIO mode under QEMU recently, generally the switch
more hurts than helps, so now only warn when DMA errors happen

code kept under ATA_DOWNGRADE_MODE ifdef, disabled by default
