qcacld-3.0: Update the occupied channel list after CSA

Currenlty the occupied channel list is not updated with the new
channel to which STA gets connected after CSA. This leads to non
updation of the scan_list in firmware with the new occupied
channel. So firmware goes for a full scan instead of partial scan
in case of roam scan trigger.

To mitigate this issue, update the occupied channel list with the
new channel after CSA, which will lead to updation of scan list in
firmware.
