crypto: sahara - use the backlog
With commit 7e77bdebff5cb1e9876c561f69710b9ab8fa1f7e crypto: af_alg - fix backlog handling in place, the backlog works under all circumstances where it previously failed, atleast for the sahara driver. Use it. Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
