spec: not clear whether VFIO_USER_DMA_WRITE should track dirty pages #751

The spec is not clear whether a vfio-user server should be still marking pages dirty when issuing a VFIO_USER_DMA_WRITE command. It is assumed so but one can assume that since the client handles the message, it knows that the pages is dirtied. We should clarify this in the spec.
