Aditya Kumar Singh 1afa18e9e7 wifi: mac80211: fix switch count in EMA beacons
Currently, whenever an EMA beacon is formed, due to is_template
argument being false from the caller, the switch count is always
decremented once which is wrong.

Also if switch count is equal to profile periodicity, this makes
the switch count to reach till zero which triggers a WARN_ON_ONCE.

Fix this issue by making the is_template argument as true when fetching
the EMA beacons.

README

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.
