net: axienet: Check for DMA mapping errors Especially with the default 32-bit DMA mask, DMA buffers are a limited resource, so their allocation can fail. So as the DMA API documentation requires, add error checking code after dma_map_single() calls to catch the case where we run out of "low" memory.
