[ Upstream commit21dfbcd1f5] In skcipher_accept_parent_nokey() the whole af_alg_ctx structure is cleared by memset() after allocation, so add such memset() also to aead_accept_parent_nokey() so that the new "init" field is also initialized to zero. Without that the initial ctx->init checks might randomly return true and cause errors. While there, also remove the redundant zero assignments in both functions. Found via libkcapi testsuite.

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.
