 SCSI fixes on 20160611
 
 Two current fixes: one affects Qemu CD ROM emulation, which stopped
 working after the updates in SCSI to require VPD pages from all
 conformant devices.  Fix temporarily by blacklisting Qemu (we can
 relax later when they come into compliance).  The other is a fix to
 the optimal transfer size.  We set up a minefield for ourselves by
 being confused about whether the limits are in bytes or sectors (SCSI
 optimal is in blocks and the queue parameter is in bytes).  This tries
 to fix the problem (wrong setting for queue limits max_sectors) and
 make the problem more obvious by introducing a wrapper function.
