[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 Signed-off-by: Dan Williams <dan.j.williams@intel.com> Acked-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
