[Merge] ~fnordahl/ubuntu/+source/openvswitch:bug/1915829 into ~ubuntu-server-dev/ubuntu/+source/openvswitch:master

[Frode Nordahl]

Thank you for the review Christian.

Updated the package version and updated the patch to now match the version merged upstream [0].

We got it backported all the way to 2.13, but I would like to proceed with carrying it as a patch in the packaging until a upstream point release is cut as there are downstream issues waiting to be resolved by this fix.

Hope this resonates well with you.
