During VF post-migration recovery, MMIO communication channel to GuC is used, despite CTB channel being enabled. This behavior is rooted in the save-restore architecture specification. Therefore, a VF driver cannot assert that CTB is disabled while sending MMIO messages to GuC. Such assertion needs to be PF only, or be removed. This patch simply removes the assertion.

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.
