[PATCH v2] xaudio2_7: Correct reference count on newly created XAudio2 object

[Alistair Leslie-Hughes]

FAudioCOMConstructWithCustomAllocatorEXT initialize the reference count
to 1, then QueryInterface increase the count to 2.  Thus the finial
release wont be called if a balanced AddRef/Release is used.
