audio: [Windows] satisfy go vet on the IStream pointer conversion

vet flagged the uintptr to pointer cast for the shell-owned COM
interface. The pointer is not Go memory so the cast is safe; converting
through the address of the uintptr expresses that without a warning and
keeps `go vet ./...` clean.
