Ilya Maximets 6cc523eaee net: openvswitch: fix skb leak on flow key update failure during ct 
commit bc62e843bc upstream.

ovs_ct_execute() always steals or frees the skb on failure while
ovs_flow_key_update() does not.  So, if it fails and we return right
away, the skb ends up leaked.

Fix that by breaking instead and letting the common error handling
code at the bottom of the loop to free the skb properly.

This is a very unlikely scenario as it requires the packet to become
unparseable by applying a set of actions on a previously parseable skb,
but should be fixed nevertheless.

Reported by Sashiko.

README 

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.
