Commit b488c766442f ("ath11k: report rssi of each chain to mac80211 for QCA6390/WCN6855")
and commit c3b39553fc77 ("ath11k: add signal report to mac80211 for QCA6390 and WCN6855")
call debugfs functions in mac ops. Those functions are no-ops if CONFIG_ATH11K_DEBUGFS is
not enabled, thus cause wrong status reported.
Move them to mac.c.
Besides, since WMI_REQUEST_RSSI_PER_CHAIN_STAT and WMI_REQUEST_VDEV_STAT stats could also
be requested via mac ops, process them directly in ath11k_update_stats_event().
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.37
Fixes: b488c766442f ("ath11k: report rssi of each chain to mac80211 for QCA6390/WCN6855")
