setupapi: SetupDiGetClassDevsExW should ignore DIGCF_ALLCLASSES if class set

The specs say that DIGCF_ALLCLASSES and class should be mutually 
exclusive, but Windows silent ignores the flag if they are both set. 
Without this patch, a bug in Rocksmith causes it to fail when 
enumerating USB devices.
