Convert smb311_update_preauth_hash() to use the SHA-512 library instead of a "sha512" crypto_shash. This is simpler and faster. With the library there's no need to allocate memory, no need to handle errors, and the SHA-512 code is accessed directly without inefficient indirect calls and other unnecessary API overhead. Remove the call to smb311_crypto_shash_allocate() from smb311_update_preauth_hash(), since it appears to have been needed only to allocate the "sha512" crypto_shash. (It also had the side effect of allocating the "cmac(aes)" crypto_shash, but that's also done in generate_key() which is where the AES-CMAC key is initialized.) For now the "sha512" crypto_shash is still being allocated elsewhere. It will be removed in a later commit.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
