Philippe Mathieu-Daudé f02b664aad hw/dma: Let dma_buf_read() / dma_buf_write() propagate MemTxResult ... Since commit 292e13142d, dma_buf_rw() returns a MemTxResult type. Do not discard it, return it to the caller. Pass the previously returned value (the QEMUSGList residual size, which was rarely used) as an optional argument. With this new API, SCSIRequest::residual might now be accessed via a pointer. Since the size_t type does not have the same size on 32 and 64-bit host architectures, convert it to a uint64_t, which is big enough to hold the residual size, and the type is constant on both 32/64-bit hosts. Update the few dma_buf_read() / dma_buf_write() callers to the new API.
