socat tunnel for nbd mirror was introduce here
https://pve.proxmox.com/pipermail/pve-devel/2017-January/024777.html
to workaround when nbd client was hanging on non responding nbd server.
We have added a 30s timeout on socat tunnel, but when we migrate
multiple disks, it can break migration if for example first disk
is already finished and don't send any new datas in the tunnel.
The connect timeout bug has been fixed in qemu 2.9,
so we can remove the socat tunnel now.
