reference IPortDMus,

create obligatory IServiceGroup and reference it

NewStream()

template<typename stream_t>

::NTSTATUS __stdcall dxd::dmus::miniport<stream_t>::NewStream(::IMXF** stream, ::IUnknown* unknown, ::POOL_TYPE, unsigned long, ::DMUS_STREAM_TYPE stream_type, ::KSDATAFORMAT* format, ::IServiceGroup** service_group, ::IAllocatorMXF* allocator, ::IMasterClock* master_clock, unsigned long long* schedule_prefetch)

Thats the only place the midiport needs the dummy IServiceGroup member for. The DMUS_STREAM_MIDI_CAPTURE stream will removed again when not providing an IServiceGroup.
