So actually I have a patch that starts to remove internal queueing from
tmscsim.  This gets rid of internal queueing for those cases where we
can just make the midlayer do the the work by returning erros from
->queuecommand (and cleans up the tmscsim queuecommand implementation
singnificantly).

Next step would get rid of the more complicated internal queueing where
we need to make the scsi layer requeue by returning appropinquate DID_
values from ->scsidone.
