Doing asynchronous probing can lead to reordered network device names.
And because udev doesn't have any useful information to construct a
persistent name, this causes VM's to sporadically boot with reordered
device names and no connectivity.
This shows up on the Ubuntu image on larger VM's where 30% of the
time eth0 and eth1 get swapped.
Note: udev MAC address policy is disabled on Azure images
because the netvsc and PCI VF will have the same mac address.
Fixes: af0a5646cb8d ("use the new async probing feature for the hyperv drivers")
