[PATCH v3] ath10k: Fix 10.4 extended peer stats update

[Mohammed Shafi Shajakhan]

From: Mohammed Shafi Shajakhan <mohammed@qti.qualcomm.com>

10.4 'extended peer stats' will be not be appended with normal peer stats
data and they shall be coming in separate chunks. Fix this by maintaining
a separate linked list 'extender peer stats' for 10.4 and update
rx_duration for per station statistics. Also parse through beacon filter
(if enabled), to make sure we parse the extended peer stats properly.
This issue was exposed when more than one client is connected and
extended peer stats for 10.4 is enabled

The order for the stats is as below
S - standard peer stats, E- extended peer stats, B - beacon filter stats

{S1, S2, S3..} -> {B1, B2, B3..}(if available) -> {E1, E2, E3..}

Fixes: f9575793d44c ("ath10k: enable parsing per station rx duration for 10.4")

This is not a hardware feature so hw_params is not really the right
place to handle this. In the pending branch I tried to solve this a bit
differently:

https://git.kernel.org/cgit/linux/kernel/git/kvalo/ath.git/commit/?h=pending&id=ecf4daadc7677518ec7185dbddab959ac6e2db96

I added a bool "extended" to struct ath10k_fw_stats which is used to
detect if extended stats are used. Would that work? Please note that I
have only compile tested the patch.

[shafi] thanks for taking time to do this, the change looks fine to me !
since 'ath10k_sta_update_rx_duration' is called right after 'ath10k_wmi_pull_fw_stats'
this should properly update the rx_duration based on the current data
