[PATCH v2 0/2] MR8646: dmcompos: Simplify the DMChordMap IPersistStream_Load() method

[Michael Stefaniuc (＠mstefani)]

After the fixes from MR!8644 Chicken Tournament parses more of its DMusic files and spits out hundreds of these messages:
```
0024:warn:dmfileraw:IDirectMusicLoaderResourceStream_IStream_Read : requested size out of range
0024:warn:dmfileraw:IDirectMusicLoaderResourceStream_IStream_Read : requested size out of range
0024:warn:dmfileraw:IDirectMusicLoaderResourceStream_IStream_Seek : requested offset out of range
0024:warn:dmfileraw:IDirectMusicLoaderResourceStream_IStream_Read : requested size out of range
```

This MR doesn't depends on MR!8644.
