liujunjie 7da2d99fb9 clean up callback when del virtqueue ... Before, we did not clear callback like handle_output when delete the virtqueue which may result be segmentfault. The scene is as follows: 1. Start a vm with multiqueue vhost-net, 2. then we write VIRTIO_PCI_GUEST_FEATURES in PCI configuration to triger multiqueue disable in this vm which will delete the virtqueue. In this step, the tx_bh is deleted but the callback virtio_net_handle_tx_bh still exist. 3. Finally, we write VIRTIO_PCI_QUEUE_NOTIFY in PCI configuration to notify the deleted virtqueue. In this way, virtio_net_handle_tx_bh will be called and qemu will be crashed. Although the way described above is uncommon, we had better reinforce it.
