In the case where a network glitch causes a packet to arrive so late that the jitter buffer has gone into expand mode, the playout timestamp could have been increased to a value that is larger than the RTP timestamp of the late packet when it finally arrives. This causes the difference to be negative, and would make the value wrap (unsigned). With this fix, the difference is set to zero when the playout timestamp is ahead of the incoming RTP timestamp. Further down in the method, a zero-value will lead to the averaging filter not being updated.
