vhost-scsi: Add missing virtio-scsi -> TCM attribute conversion
commit 46243860806bdc2756f3ce8ac86b4d7c616bcd6c upstream.
While looking at hch's recent conversion to drop the MSG_*_TAG
definitions, I noticed a long standing bug in vhost-scsi where
the VIRTIO_SCSI_S_* attribute definitions where incorrectly
being passed directly into target_submit_cmd_map_sgls().
This patch adds the missing virtio-scsi to TCM/SAM task attribute
conversion.
