This happens in tests newly added by Andrew (dmusic: Support creating 
default ports with GUID_NULL).
In his test, the dwSize member of the structure DMUS_PORTCAPS is not 
initialized before getting port caps
This worked because before my patch only the Microsoft Synthetizer is 
enumerated and caps returned by the Synth GepCaps
sets the dwSize member.
I can sets the dwSize in my code but normally it's up to the caller to 
set the dwSize member. The callee should copy the number
of bytes specified by dwSize or just return an error.
