wifi: rtw89: coex: When Bluetooth not available don't set power/gain

If Bluetooth is working, it will update their info regularly. And the code
will increase the counters while the info updating. Use this counter to
judge is Bluetooth working or not. Don't need to set Bluetooth power or
gain when it is not working.
