crypto: shash - introduce crypto_grab_shash()
Currently, shash spawns are initialized by using shash_attr_alg() or crypto_alg_mod_lookup() to look up the shash algorithm, then calling crypto_init_shash_spawn(). This is different from how skcipher, aead, and akcipher spawns are initialized (they use crypto_grab_*()), and for no good reason. This difference introduces unnecessary complexity. The crypto_grab_*() functions used to have some problems, like not holding a reference to the algorithm and requiring the caller to initialize spawn->base.inst. But those problems are fixed now. So, let's introduce crypto_grab_shash() so that we can convert all templates to the same way of initializing their spawns.
