During vm boot, there might be possibility that vf registration call
comes before the vf association from host to vm.
And this might break netvsc vf path, this is in order to prevent the
same block vf registration until vf bind message comes from host.
[Test Plan]
Microsoft tested
[Where things could go wrong]
The 5.4 backport patch could hang waiting for a VF addition to complete.
