agent: slave ap follows slave bsta
This is fix for scenario where master 5G AP starts on DFS channel. Slave device can not start beaconning at this DFS channel directly after bsta connection, because on slave this channel could not have CAC done yet. Solution for that is to connect bsta of slave to master 5G AP only to get channel numer and then disconnect bsta. Then switch to the same channel master 5G works on, perform CAC if not done yet, and enable 5G AP on slave. So in other words: slave 5G AP channel follows slave bsta channel which is connected to master at dfs channel.
