vhost_net: zerocopy: fix possible NULL pointer dereference of vq->bufs When we want to disable vhost_net backend while there's a tx work, a possible NULL pointer defernece may happen we we try to deference the vq->bufs after vhost_net_set_backend() assign a NULL to it. As suggested by Michael, fix this by checking the vq->bufs instead of vhost_sock_zcopy(). Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
