Done.

Just doing some debugging using scsi_debug and noticed
that 'blockdev --rereadpt /dev/sdb' causes a SCSI
REPORT SUPPORTED OPERATION CODES command to be issued.
Perhaps we could add that one (and ... SUPPORTED TMFs) to
scsi_debug's code.

I was also testing setting the SWP bit in the Control
mode page and that works, even though that field is
marked as 'changeable=n'. Since scsi_debug allows all
fields in that page to be changed, perhaps they could
all be marked as changeable.
