In MLO STA 2.4 GHz + 5 GHz High band and SAP concurrency case,
5 GHz Low band SAP will move to MLO 5 GHz link's home channel for
SCC after MLO STA is up.
But GO starts on 5 GHz high band when SAP CSA is in process and
pass the policy mgr concurrency check because the SAP channel
is still 5 GHz low band.
Fix by defer GO BSS start if any CSA is in progress and also
check any AP start is pending for STA, SAP force SCC concurrency
handling.
