See if we need to request sense information. if so, then get it
now, so we have a better idea of what to do.
</p></div><div class="refsect1" title="Notes"><a id="id2700250"></a><h2>Notes</h2><p>
This has the unfortunate side effect that if a shost adapter does
not automatically request sense information, we end up shutting
it down before we request it.
</p><p>
All drivers should request sense information internally these days,
so for now all I have to say is tough noogies if you end up in here.

Long term this code should go away, but that needs an audit of
all LLDDs first.
