Fix this by using the primary GT in the macro. Note that this WA only applies to PXP and we don't yet support that in Xe, so there are no negative effects to this bug, which is why we didn't see any errors in testing. v2: use the primary GT in the macro instead of marking the WA as platform-wide (Lucas, Matt).
