drm/i915/guc: Enable CT_DEAD output in regular debug builds
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.
