vcl svm: fix rx event loss
When vcl_epoll_wait_handle_mq handles rx events exceeding maxevents, VPP will not signal because cursize > 0, and the remaining rx events cannot be triggered because the eventfd event has been read. Therefore, we should dequeue all events until cursize = 0. And then handle msg up to maxevents with vcl_epoll_wait_handle_mq_event and those beyond with vcl_handle_mq_event.
Type: fix
