Log exception when MediaPlayer.attemptDataSource fails

This gives more context when a subsequent fallback call to
setDataSource(String, Map<String, String>, List<HttpCookie>) fails
(which is often expected, especially for content:// URIs). These logs
should help to see more detail of the unexpected failure from
ContentResolver in this case.
