crypto: skcipher - Fix request for sync algorithms
When a sync givcipher algorithm is requested, if an async version of the same algorithm already exists, then we will loop forever without ever constructing the sync version based on a blkcipher. This is because we did not include the requested type/mask when getting a larval for the geniv algorithm that is to be constructed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
