mpdparser: Only check stream->segments for a repeated last segment if we have a static list of segments

Otherwise we'll crash, trying to derefence NULL. And if we have no static list
of segments, we can't have repeated segments anyway.

Regression introduced by cfe2871a5e3c5b1db20470927642b776e055a87a
