Commit afbab6e4e88d ("wifi: ath12k: modify ath12k_mac_op_bss_info_changed()
for MLO") replaced the bss_info_changed() callback with vif_cfg_changed()
and link_info_changed() to support Multi-Link Operation (MLO). As a result,
the station power save configuration is no longer correctly applied in
ath12k_mac_bss_info_changed().
Move the handling of 'BSS_CHANGED_PS' into ath12k_mac_op_vif_cfg_changed()
to align with the updated callback structure introduced for MLO, ensuring
proper power-save behavior for station interfaces.
Tested-on: WCN7850 hw2.0 PCI WLAN.IOE_HMT.1.1-00011-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1
Fixes: afbab6e4e88d ("wifi: ath12k: modify ath12k_mac_op_bss_info_changed() for MLO")
