kernel: Update to 4.13.9/4.9.58/4.4.94

Note: There were more conflicts in applying the
vmbus patches to 4.13. For now I've just skipped the
conflicting patches so the end-result may be that
Hyper-V sockets on 4.13 may break (if they were not
already broken by the update to 4.13.6).

-A just-closed channel may have a pending interrupt, and later when a new
