iwlwifi: mvm: overwrite skb info later

commit bd05a5bd6b11d7fd26a668de83c5cb996de05f8f upstream.

We don't really need clear the skb's status area nor store the
dev_cmd into it until we really commit to the frame by handing
it to the transport - defer those operations until just before
we do that.

This doesn't entirely fix the bug with frames not getting sent
out after having been deferred due to DQA, because it doesn't
restore the info->driver_data[0] place that was already set to
zero (or another value) by the A-MSDU logic.
