[CRYPTO] scatterwalk: Restore custom sg chaining for now
Unfortunately the generic chaining hasn't been ported to all architectures yet, and notably not s390. So this patch restores the chainging that we've been using previously which does work everywhere. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
