vhost: fix vring requests validation broken if no FDHEADmaster
When VHOST_USER_VRING_NOFD_MASK is set, the fd_num is 0, so validate_msg_fds() will return error. In this case, the negotiation of vring message between vhost user front end and back end would fail, and as a result, vhost user link could NOT be up. How to reproduce: 1.Run dpdk testpmd insides VM, which locates at host with ovs+dpdk. 2.Notice that inside ovs there are endless logs regarding failure to handle VHOST_USER_SET_VRING_CALL, and link of vm could NOT be up.
