crypto: sun8i-ss - call finalize with bh disabled
Doing ipsec produces a spinlock recursion warning. This is due to not disabling BH during crypto completion function. Fixes: f08fcced6d00 ("crypto: allwinner - Add sun8i-ss cryptographic offloader") Signed-off-by: Corentin Labbe <clabbe@baylibre.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
