[SCSI] libsas,libata: fix ->change_queue_{depth|type} for sata devices
Pass queue_depth change requests to libata, and prevent queue_type
changes for ATA devices.
Otherwise:
1/ we do not honor the libata specific restrictions on the queue depth
2/ libsas drivers that do not set sdev->tagged_supported are unable to
change the queue_depth of ata devices via sysfs
