lib/crypto: blake2s: Adjust parameter order of blake2s()

Reorder the parameters of blake2s() from (out, in, key, outlen, inlen,
keylen) to (key, keylen, in, inlen, out, outlen).

This aligns BLAKE2s with the common conventions of pairing buffers and
their lengths, and having outputs follow inputs.  This is widely used
elsewhere in lib/crypto/ and crypto/, and even elsewhere in the BLAKE2s
code itself such as blake2s_init_key() and blake2s_final().  So
blake2s() was a bit of an exception.

Notably, this results in the same order as hmac_*_usingrawkey().

Note that since the type signature changed, it's not possible for a
blake2s() call site to be silently missed.
