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.

Fixes bug https://bugs.winehq.org/show_bug.cgi?id=14193
