crypto: shash - Add __crypto_shash_cast
This patch adds __crypto_shash_cast which turns a crypto_tfm into crypto_shash. It's analogous to the other __crypto_*_cast functions. It hasn't been needed until now since no existing shash algorithms have had an init function. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
