qcacld-3.0: Avoid wait for hw mode change during SAP CSA

The SAP channel change can be called in scheduler thread and thus
waiting for hw mode change in scheduler thread will always lead to
timeout and thus channel switch failure.

Fix is to avoid wait and continue channel switch after hw mode
change is completed.
