The sizeof(*ctx->dec_cd) and sizeof(*ctx->enc_cd) are equal,
but we should use the correct one for freeing memory anyway.

Some code cleanups after crypto API changes:
- Change qat_algs_unregister to a void function to keep it consistent
with qat_asym_algs_unregister.
- Remove empty functions qat_algs_init & qat_algs_exit.

The qat driver uses crypto_aead_crt in order to get the authsize.
This patch replaces it with the crypto_aead_authsize helper instead.

This patch converts qat to the new AEAD interface. IV generation
has been removed since it's equivalent to a software implementation.

This patch uses the crypto_aead_set_reqsize helper to avoid directly
touching the internals of aead.

The patch ad511e260a (crypto: qat -
Fix incorrect uses of memzero_explicit) broke hashing because the
code was in fact overwriting the qat_auth_state variable.
In fact there is no reason for the variable to exist anyway since
all we are using it for is to store ipad and opad. So we could
simply create ipad and opad directly and avoid this whole mess.

memzero_explicit should only be used on stack variables that get
zapped just before they go out of scope.
This patch replaces all unnecessary uses of memzero_explicit with
memset, removes two memzero_explicit calls altogether as the tfm
context comes pre-zeroed, and adds a missing memzero_explicit of
the stack variable buff in qat_alg_do_precomputes. The memzeros
on ipad/opad + digest_size/auth_keylen are also removed as the
entire auth_state is already zeroed on entry.

In a system with NUMA configuration we want to enforce that the accelerator is
connected to a node with memory to avoid cross QPI memory transaction.
Otherwise there is no point in using the accelerator as the encryption in
software will be faster.

Replaced the use of a Variable Length Array In Struct (VLAIS) with a C99
compliant equivalent. This patch allocates the appropriate amount of memory
using a char array using the SHASH_DESC_ON_STACK macro.
The new code can be compiled with both gcc and clang.
