drm/msm: fix ->last_fence() after recover
It is no longer true that we discard all in-flight submits on recover
(these days we only discard the first one that hung). After the first
re-submitted batch completes it would overwrite the fence with a correct
value, but there would be a window of time which showed all re-submitted
batches as already complete.
