You should set publish_tf parameter of rgbd_odometry node to false.

<node package="rtabmap_ros" type="rgbd_odometry" name="rgbd_odomerty">
   <param name="publish_tf" type="bool" value="false"/>
   ...
</node>

Odometry topic is mandatory for rtabmap, not for rtabmapviz. The odometry topic is not used by rtabmap only if odom_frame_id parameter is set:

~odom_frame_id (string, default: "")

The frame attached to odometry. If empty, rtabmap will subscribe to odom topic to get odometry. If set, odometry is got from tf (in this case, a covariance of 1 is used).

cheers
