[saikishor]

This was introduced by error in my previous PR: #2102

$ ros2 control list_controllers 
forward_position_controller forward_command_controller/ForwardCommandController  active
	update_rate: 10 Hz
	is_async: False
position_controller         passthrough_controller/PassthroughController         active
	update_rate: 10 Hz
	is_async: False
joint2_position_controller  passthrough_controller/PassthroughController         active

joint1_position_controller  passthrough_controller/PassthroughController         active

	is_async: False
joint_state_broadcaster     joint_state_broadcaster/JointStateBroadcaster        active
