Update gvnic driver code

[Khaled El Mously]

The GCE internal team responsible for gVNIC would like to have driver updates backported for both Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.

[Impact]
Missing functionality from the Google gvnic driver

[Test Plan]
Confirm that gvnic module still loads and operates the gvnic driver. More extensive testing done by the gvnic developers at GCE

[Regression potential]
Possible regression in gvnic behaviour or functionality. Changes are confined to the gvnic driver code so regression potential is limited to gvnic only.

List of changes:
