Barnabás Czémán 6200d947f0 wifi: wcn36xx: fix channel survey memory allocation size
KASAN reported a memory allocation issue in wcn->chan_survey
due to incorrect size calculation.
This commit uses kcalloc to allocate memory for wcn->chan_survey,
ensuring proper initialization and preventing the use of uninitialized
values when there are no frames on the channel.

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 reStructuredText 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.
