>From gen6, the hardware tracks address lookup failures and so that we do not trigger false positives from errors before we are initialised we clear those upon startup (intel_uncore_early_sanitize()). However, this is actually before we have the engines defined and this turns out to be a nop. The earliest we can do so is inside intel_engine_setup().
