crypto: ahash - Handle partial blocks in API
Provide an option to handle the partial blocks in the ahash API.
Almost every hash algorithm has a block size and are only able
to hash partial blocks on finalisation.
As a first step disable virtual address support for algorithms
with state sizes larger than HASH_MAX_STATESIZE. This is OK as
virtual addresses are currently only used on synchronous fallbacks.
This means ahash_do_req_chain only needs to handle synchronous
fallbacks, removing the complexities of saving the request state.
Also move the saved request state into the ahash_request object
as nesting is no longer possible.
Add a scatterlist to ahash_request to store the partial block.
