The function is only used from within GEM_BUG_ON(), which is causing
warnings with Wunneeded-internal-declaration in some builds. Since the
function is a simple wrapper around a CT function, we can just call the
CT function directly instead.

Fixes: 2be5d86f631f ("drm/i915/guc: skip disabling CTBs before sanitizing the GuC")
