RFC - msacm32: Quit on unsupported destination format in PCM_FormatSuggest

[Bruno Jesus]

Since this DLL is far away from my comprehension I'm first sending
this to wine-devel.

Current code [1] suggest that only WAVE_FORMAT_PCM is supported so do
not allow the function to succeed if the destination format is not
PCM.

 860             WARN("not possible\n");
 861             return ACMERR_NOTPOSSIBLE;
 862         }
 863         adfs->pwfxDst->wFormatTag = adfs->pwfxSrc->wFormatTag;
 864     }
