hw/virtio/vhost-backend: Fix Coverity CID 1432871
Fix uninitialized value issues reported by Coverity: Field 'msg.reserved' is uninitialized when calling write(). While the 'struct vhost_msg' does not have a 'reserved' field, we still initialize it to have the two parts of the function consistent. Reported-by: Coverity (CID 1432864: UNINIT) Fixes: c471ad0e9bd ("vhost_net: device IOTLB support") Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20201103063541.2463363-1-philmd@redhat.com> Reviewed-by: Stefano Garzarella <sgarzare@redhat.com> Reviewed-by: Michael S.
