LinuxKPI: 802.11: mac80211 ops: distinguish between {bss,link}_info_changed

With MLO and multi-link setups if avail we want to call link_info_changed
whereas for legacy drivers we still need to call bss_info_changed.
While we currently do not (yet) support multi-link configurations
we still need to drive the correct commands to satisfy firmware
requirements.
