Bug description:
  On proposed 4.13.0-1001.1 linux-azure kernel reloading the netvsc
  module will cause the VM network to stop working on WS2016.

  Manual repro is easy, start a VM with that kernel and run:
  modprobe -r hv_netvsc
  modprobe hv_netvsc

  At this point the command will hang and after 2 minutes the hung task
  messages will appear.

  Test env info:
  - ubuntu 16.04.3
  - Affected platforms: 
  a) WS2016 and WS2016 fall update - 1709
  b) WS2012R2

  4.11 series linux-azure are not showing this behavior.
