Hartmut Brandt e557905435 Fix a problem in bus_dmamap_load_{mbuf,uio} when the first mbuf or the first 
uio segment is empty. In this case no dma segment is create by
bus_dmamap_load_buffer, but the calling routine clears the first flag.
Under certain combinations of addresses of the first and second mbuf/uio
buffer this leads to corrupted DMA segment descriptors. This was already
fixed by tmm in sparc64/sparc64/iommu.c.
