Fix two issues with streaming OGG/Vorbis

Browse Source 
- In certain cases, padding was present at the end of streams causing noticeable clicking when looped. This is handled by truncating the stream to its actual size.
 - When playing an ogg stream without stream cache, an exception would be raised since the stream was closed prematurely
