So, for HBA hardware that automatically does the request-sense (i.e.
BusLogic, etc.), the mid-layer should be able to handle that.  That
is, if there is an error, and XS_SENSE is in the scsipi_xfer error word,
then the mid-layer should *NOT* request sense again :-)

For HBA hardware that requires software to do it (i.e. the 53c9x, etc.),
the the mid-layer should do it and HBA drivers should not.
