gst-examples: webrtc: signalling: simple-server Fix condition when calling a busy...

When a session request is coming in, ERROR occurs when the callee is busy.
But peer_status is the status of the caller, which is of course None when
calling someone, while self.peers[callee_id][2] is that of the callee.
