disk: In "superfloppy" mode, create a fake partition entry

Browse source 
We normally create a table of the partition sizes/types present
on a drive.  Howeever, if the drive is set up as a "superfloppy",
where there is no partition table and a single filesystem starting
at sector 0, this "pinfo" table is not populated.

So now, populate the pinfo table with a single entry that matches
the filesystem type, start, and size.
