The entire completions suppress mechanism is currently broken because the HCA might retry a send operation (due to dropped ack) after the nvme transaction has completed.
In order to handle this, we signal all send completions and introduce a separate done handler for async events as they will be handled differently (as they don't include in-capsule data by definition).
