This is patch as384.  It reverts some of our sanity checks on the GetMaxLUN
part of the Bulk-only protocol.  Apparently, this is one area where vendors
can't even get close to correct.  So, in the face of any sort of error, we
assume a single LUN.

We also include some comments so we don't make this mistake again.
