Moshe Shemesh e99c687322 net/mlx5e: CT: Fix null-ptr-deref in add rule err flow 
In error flow of mlx5_tc_ct_entry_add_rule(), in case ct_rule_add()
callback returns error, zone_rule->attr is used uninitiated. Fix it to
use attr which has the needed pointer value.

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 reStructuredText 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.
