Reimplement bus_dmamap_load with bus_dmamap_load_buffer.
Previously it didn't honor parent dma tag's restrictions such that an invalid dma segment could be passed to device. The driver for the device may panic in sanity check routine for the dma segment or may produce unexpected results. I have no idea how it could ever have worked before.
