oggdec: simplify start time calculation code.
Also slightly more correct behaviour in case streams_left for some reason is 0 from the start. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> (cherry picked from commit a4163b2d6583396845e06b1b976c3a981eb8cb1c) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
