Don't force HRESULT status to DSERR_BUFFERLOST by default in primarybuffer_SetFormat function.
Assign to it S_OK instead, as done in current Wine:
a8583acae9:/dlls/dsound/primary.c#l440
That variable is already set to failure in other appropriate place, when this is indeed needed:
https://git.reactos.org/?p=reactos.git;a=blob;h=b04a526929e4e817ff63aa652530e5901a3253a6;f=dll/directx/wine/dsound/primary.c#l511
The assigned failure status caused executing failure handling code even when the fail actually didn't happen.
In particular, DSOUND_ReopenDevice failed on waveOutOpen call when calling this was not needed.
After my changes, it's called only when needed, i. e., only when the actual failure happens
Otherwise, if all goes good, that code is not called, so the data is transfered successfully and the function is working correctly.
It fixes non-working playback in QMMP 0.11.1 (via DirectSound ouput plugin) and AIMP 3.10 and newer versions.
Also it improves the DirectSound test results from MS DxDiag: now all 4 available tests are passing successfully, instead of only 2.
Other dsound issues also might be fixed as well.
