hw/vfio: Access MemoryRegion with MemOp
The memory_region_dispatch_{read|write} operand "unsigned size" is being converted into a "MemOp op". Convert interfaces by using no-op size_memop. After all interfaces are converted, size_memop will be implemented and the memory_region_dispatch_{read|write} operand "unsigned size" will be converted into a "MemOp op". As size_memop is a no-op, this patch does not change any behaviour.
