A couple more small cleanups to the BLAKE2s code before these things get
propagated into the BLAKE2b code:
- Drop 'const' from some non-pointer function parameters. It was a bit
excessive and not conventional.
- Rename 'block' argument of blake2s_compress*() to 'data'. This is for
consistency with the SHA-* code, and also to avoid the implication
that it points to a singular "block".
No functional changes.
