vhost/scsi: Convert completion path to use copy_to_iter

Required for ANY_LAYOUT support when the incoming virtio-scsi response
header + fixed size sense buffer payload may span more than a single
iovec entry.

This changes existing code to save cmd->tvc_resp_iov instead of the
first single iovec base pointer from &vq->iov[out].
