wifi: mac80211_hwsim: avoid warning with MLO PS stations

Browse source 
If the station disables all links it's in powersave and
we shouldn't transmit anything to it, but we don't handle
that correctly yet. For now, just avoid the warning, once
we really add support for this case we can revert to the
old warning.
