* [dpdk-stable] [PATCH v2] vhost: fix vring message handling broken in some case

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.

Fixes: bf47225 ("vhost: fix possible denial of service by leaking FDs")

The title can be changed while applying if you agree with it, no need to
send v3.

I'll take care of the different backports.

Thanks, could you provide the qemu command line you used to reproduce
the issue, and also the kernel version?

It will help to document the commit message.

Both host and VM use CentOS7.4 with kernel 3.10.0-693.el7.x86_64. 
Testpmd insides VM uses DPDK18.11.

For the title, aligning to backport patches:
"vhost: fix vring requests validation broken if no FD"
