Wafer 33abfea239 hw/virtio: Fix obtain the buffer id from the last descriptor ... The virtio-1.3 specification <https://docs.oasis-open.org/virtio/virtio/v1.3/virtio-v1.3.html> writes: 2.8.6 Next Flag: Descriptor Chaining Buffer ID is included in the last descriptor in the list. If the feature (_F_INDIRECT_DESC) has been negotiated, install only one descriptor in the virtqueue. Therefor the buffer id should be obtained from the first descriptor. In descriptor chaining scenarios, the buffer id should be obtained from the last descriptor.
