Hmm, this needs updating for the batch/state split; and of particular
note that the batch->bo is no longer constant. It shouldn't matter
overall as the contents/offsets are preserved.
I would need to go back and see why you need to know the handle before
the submit, but the obvious solution to me would be to record the
submission.

Fwiw, invalid handle is 0.
