From: Ashok Raj Nagarajan <arnagara at codeaurora.org>
BugLink: https://bugs.launchpad.net/bugs/1879633
This patch add supports to reset the per peer htt stats.
Usage:
echo 1 > /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/stations/<peer MAC addr>/htt_peer_stats_reset
While doing so, sync the wmi services between FW and host.
