drm/xe: Bypass Wa_14018094691 when primary GT is disabled 



Don't try to lookup Wa_14018094691 on a NULL GT when the primary GT is
disabled.  Since this whole workaround centers around mid-thread
preemption behavior, the workaround isn't relevant if the primary GT
(where the engines that can do MTP live) is disabled.
