This works only for non-ML station. Now that MLO support is there, extend this function to use link sta instead of deflink. Additionally, in ath12k_mac_handle_link_sta_state(), the link sta structure is not accessible, making it difficult to fetch the bandwidth there. However, ath12k_mac_station_assoc() does reference the link sta structure. Therefore, move the initial assignment of the arsta bandwidth member to ath12k_mac_station_assoc().
