Fix Wrong Result In Debug Message For SDP Origin Processing

While looking at some debug logs, I noticed that it was being reported that the
SDP origin line was unsupported or failed.  Upon looking into this on my local
machine, I found that I too was getting this debug message yet everything seemed
to be getting processed properly.  What was discovered is, that, the variable to
determine what is displayed in the debug message for the SDP line that was
processed, was not being set for the origin line when the result was successful.

This patch fixes this and was tested on local machine.
