After driver sets the missed chain on the tc skb extension it is
consumed (deleted) by tc_classify_ingress and tc jumps to that chain.
If tc now misses on this chain (either no match, or no goto action),
then last executed chain remains 0, and the skb extension is not re-added,
and the next datapath (ovs) will start from 0.
Fix that by setting last executed chain to the chain read from the skb
extension, so if there is a miss, we set it back.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
