Well, dma_buf_rw() is the only one that needs change, and it is
static, so the importance is not so great. However, more importantly,
dma_buf_rw() still uses cpu_physical_memory_rw() because I missed
switching it to the universal wrappers. I'll fix that up as well as
the DMADirection stuff in the next spin of the patch adding DMAContext
awareness to sglists and the rest.
