sna: Upon unwinding operations, also check for exec objects to clear

If we cancel an operation after partially committing it, we may leave
the batch bookkeeping in an inconsistent state with an exec object with
a zero-length batch. Ordinarily, this would not be an issue as we could
pass the extra object to the next batch. However, if we switch rings, we
need to clear the extra objects as they are currently flagged as being
on the wrong ring, leading to hilarity.
