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.
