Initialize QRhiD3D12::activeAdapter for imported device path

Browse Source 
This commit makes it so the QRhiD3D12::activeAdapter is set when
using an imported device. QD3D12MemoryAllocator::create would
crash before as it would attempt to call IDXGIAdapter1::GetDesc1
on the passed uninitalized pointer. With this change using an
imported device with the d3d12 rhi backend will no longer crash
the application.
