Fix compilation on sparc64 by actually supplying the bus_dma_tag_t member

Browse Source 
of the rx_ring to bus_dmamap_sync(9). Given that netmap code tries to
obtain the bus addresses of netmap buffers via vtophys(9) instead of using
bus_dma(9) it currently has zero chance of actually working on sparc64
though (and for that matter f.e. also not with MACs limited to 32-bit DMA
on x86 machines with more than 4GB of RAM).
