Dongliang Mu 984cfd55e0 net: ieee802154: remove an unnecessary null pointer check
llsec_parse_seclevel has the null pointer check at its begining. Compared
with nl802154_add_llsec_seclevel, nl802154_del_llsec_seclevel has a
redundant null pointer check of info->attrs[NL802154_ATTR_SEC_LEVEL]
before llsec_parse_seclevel.

Fix this issue by removing the null pointer check in
nl802154_del_llsec_seclevel.

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.
