This patch fixes two issues observed during self tests with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled. 1. gcm(aes) hang issue , that happens during decryption. 2. rfc4106-gcm-aes-chcr encryption unexpectedly succeeded. For gcm-aes decryption , authtag is not mapped due to sg_nents_for_len(upto size: assoclen+ cryptlen - authsize). So fix it by dma_mapping authtag. Also replaced sg_nents() to sg_nents_for_len() in case of aead_dma_unmap(). For rfc4106-gcm-aes-chcr, used crypto_ipsec_check_assoclen() for checking the validity of assoclen.

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 Restructured Text 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.
