[PATCH v2 04/11] crypto: blake2b - update file comment

[Eric Biggers <ebiggers@kernel.org>]

From: Eric Biggers <ebiggers@google.com>

The file comment for blake2b_generic.c makes it sound like it's the
reference implementation of BLAKE2b with only minor changes.  But it's
actually been changed a lot.  Update the comment to make this clearer.
