The per-wiphy radio-mask loops iterated all MLDs without checking the phy,
so a stop/start or status query for one wiphy touched MLDs on another wiphy
with the same radio index (clearing present bits, tearing links down, or
reporting a foreign MLD). Skip MLDs that do not belong to the phy, matching
mld_update_phy().
