Previously, if user space keeps sending abnormal wqe, queue.prod will keep increasing while queue.index doesn't. Once queue.index==queue.prod in next round, req_next_wqe() will treat queue as empty. In such case, no new completion would be generated. Update wqe_index for each wqe completion so that req_next_wqe() can get next wqe properly.
