Non-MLO station frames are dropped in Rx path due to the condition
check in ieee80211_rx_is_valid_sta_link_id(). In multi-link AP scenario,
non-MLO stations try to connect in any of the valid links in the ML AP,
where the station valid_links and link_id params are valid in the
ieee80211_sta object. But ieee80211_rx_is_valid_sta_link_id() always
return false for the non-MLO stations by the assumption taken is
valid_links and link_id are not valid in non-MLO stations object
(ieee80211_sta), this assumption is wrong. Due to this assumption,
non-MLO station frames are dropped which leads to failure in association.
Fix it by removing the condition check and allow the link validation
check for the non-MLO stations.
