From: Sultan Alsawaf <sultan@xxxxxxxxxxxxxxx>
The conversion from bss_info_changed() to vif_cfg/link_info_changed()
removed a call to iwl_mvm_bss_info_changed_station_common() from what
became the vif_cfg_changed() path. As a result, BSS_CHANGED_PS and other
power save changes sent via ieee80211_vif_cfg_change_notify() are ignored
for MLD, which breaks power save entirely. This has a noticeable impact on
power consumption, causing idle package power to hover at 10 W on my
i9-13980HX laptop with an AX210 while connected to WiFi.
Add the missing iwl_mvm_bss_info_changed_station_common() call to the
vif_cfg_changed() path to fix power save for MLD. This brings idle package
power down to 1 W on my laptop, a 9 W improvement.
