Currently ath11k_debugfs_fw_stats_process() is using static variables to count
firmware stat events. Taking num_vdev as an example, if for whatever reason (
say ar->num_started_vdevs is 0 or firmware bug etc.) the following condition
(++num_vdev) == total_vdevs_started
is not met, is_end is not set thus num_vdev won't be cleared. Next time when
firmware stats is requested again, even if everything is working fine, we will
fail due to the condition above will never be satisfied.
The same applies to num_bcn as well.
Change to use non-static counters so that we have a chance to clear them each
time firmware stats is requested. Currently only ath11k_fw_stats_request() and
ath11k_debugfs_fw_stats_request() are requesting firmware stats, so clear
counters there.

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.
