Improve debugging a little bit:
1.  Dump the DMA memory when busdma_sync is called (BUSDMA_DEBUG). We
    should probably limit it to 64 bytes or so.
2.  Fail hard when we query segmnts and things aren't quite right.
3.  When loading a buffer, preserve the virtual address for now. I
    don't like loosing information in the process. Then again, the
    load operation is impacted if we're unwilling to forget about
    the accidental virtual mapping -- the physical address is really
    all we care about.
