Michal Wajdeczko a4e7fda489 drm/xe/guc: Always add CT disable action during second init step 
[ Upstream commit 955f3bc4af ]

On DGFX, during init_post_hwconfig() step, we are reinitializing
CTB BO in VRAM and we have to replace cleanup action to disable CT
communication prior to release of underlying BO.

But that introduces some discrepancy between DGFX and iGFX, as for
iGFX we keep previously added disable CT action that would be called
during unwind much later.

To keep the same flow on both types of platforms, always replace old
cleanup action and register new one.

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.
