The X.509 parser always sets cert->pub->pkey_algo on success, since x509_extract_key_data() is a mandatory action in the X.509 ASN.1 grammar, and it returns an error if the algorithm is unknown. Thus, remove the dead code which handled this field being NULL. This results in the ->unsupported_key flag never being set, so remove that too.

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.
