[jak3] Fix issue where some vag streams never queue (#3805)

Accidentally incrementing `s` twice in the loop, so queued streams in
slot 1, and 3 were skipped by the overlord.
This would usually cause the audio to never start playing because the
game would wait for the audio to successfully get queued.
