    [DSOUND] Don't force status to failure by default in primarybuffer_SetFormat
(#3911)
    
    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:
   
https://source.winehq.org/git/wine.git/blob/a8583acae9548e6340d8400ec771013…
    
    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=b04a526929e4e817ff63aa65253…
    
    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.
