[PATCH v3] dsound: Notify DSBPN_OFFSETSTOP earlier.

[Hiroki Awata]

Some games may not receive the DSBPN_OFFSETSTOP event and get stuck if CloseHandle is called immediately after IDirectSoundBuffer::Stop.
To solve this problem, IDirectSoundBuffer::Stop will immediately notify the DSBPN_OFFSETSTOP event.
