Define struct shash_instance in a way analogous to struct
skcipher_instance, struct aead_instance, and struct akcipher_instance,
where the struct is defined to include both the algorithm structure at
the beginning and the additional crypto_instance fields at the end.
This is needed to allow allocating shash instances directly using
kzalloc(sizeof(*inst) + sizeof(*ictx), ...) in the same way as skcipher,
aead, and akcipher instances. In turn, that's needed to make spawns be
initialized in a consistent way everywhere.
Also take advantage of the addition of the base instance to struct
shash_instance by simplifying the shash_crypto_instance() and
shash_instance() functions.
