This is a newer API that is intended for decoders like the cuvid wrapper. Until now, the wrapper required to set an awkward "incomplete" hw_frames_ctx to set the device. Now the device can be set directly, and the user can get AV_PIX_FMT_CUDA output for a specific device simply by setting hw_device_ctx. This still does a dummy ff_get_format() call at init time, and should be fully backward compatible.
