... at least not in that place, because this can also fire for
requests which have completed. Which then hits the assert in
dma_fence_set_error.
Since I'm not really clear what should be done here I pinged Chris,
and he suggested we simply remove this for now.
Found while stress-testing gpu reset using kms_busy, with about 0-3
hits of it per complete run on my snb here.
Testcase: igt/kms_busy.

My idea was the patch this morning to shuffle engine_stalled around as
we are no longer getting here for innocent engines.
