With MLO sta change, when WLAN_FEATURE_11BE_MLO is undefined, non mlo sta
index array is got wrongly, sta+sta dbs check based on it is wrong too,
and policy_mgr_concurrent_sta_doing_dbs always return false, then
2nd STA RSO is failed to enable, vdev level pcl isn't configured too, 1st
STA can roam to all band.
