crypto: authenc - Fix zero-length IV crash As it is if an algorithm with a zero-length IV is used (e.g., NULL encryption) with authenc, authenc may generate an SG entry of length zero, which will trigger a BUG check in the hash layer. This patch fixes it by skipping the IV SG generation if the IV size is zero. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
