Don't allow release wait for HLE delays.

Although, presumably the thread would stop waiting, I guess the HLE func
in most cases probably checks and re-waits?

Fixes breakage in Jeanne d' Arc, which constantly releases from wait the
main thread, but calls things like sceMpegCreate which do block.
Forget blocking audio threads that die/release.
