reverting previous fix. This doesn't solve all conditions.
I need to add a telemetry_switch conf or feature to solve enabling MSP over FRSKy with switch not activated when armed ( i.e. using bt serial for tuning sessions ), but it will break when not using telemetry switch.
Better to keep it like this for now.
Added a mcfg.telemetry_switch for CLI
If telemetry_switch=1 it change baudrate and protocol using aux channel, either it switch  when armed/disarmed.

This allows to keep MSP serial while armed for BT dongle if needed.
