There is a sporadic failure to enable CTs ocurring in CI on one specific machine that can't be reproduced locally. The driver already supports dumping out a whole bunch of GuC related debug info on such a failure but only when the verbose GuC debug config option is enabled. It would be preferable to not enable all the verbose debug output. So just bump the CT_DEAD code to regular I915 debug level rather than GUC debug level, at least temporarily for CI. To prevent excessive spam in other parts of CI, also add a check against doing a CT_DEAD dump during an error injection test. No point in dumping large amounts of 'why did this fail' info when the fail is deliberately induced. v2: Revert accidentally enabling some other verbose debug output.

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.
