[dpdk-dev] [PATCH v2 1/5] lib_vhost: Fix enqueue/dequeue can't handle chained vring descriptors

Vring enqueue need consider the 2 cases: 1. Vring descriptors chained together, the first one is for virtio header, the rest are for real data, virtio driver in Linux usually use this scheme; 2. Only one descriptor, virtio header and real data share one single descriptor, virtio-net pmd
