libata: fix ata_scsi_change_queue_depth() Fix ata_scsi_change_queue_depth() such that... * NCQ on/off is exactly determined using the same logic as the issue path. * queue depth is adjusted to 1 if NCQ is not enabled. * -EINVAL is returned if requested action is ignored due to limitations. This fixes the bug which allows queue depth to be increased on blacklisted NCQ hosts/devices. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
