target: Fix reporting of supported VPD pages

Browse source

The current handling of VPD page 00h (Supported VPD Pages) for INQUIRY
commands has a couple of problems:

 - The page length field is incorrectly set to 3, so the entry for 86h
   (Extended INQUIRY Data) is ignored since it is in the fourth slot.
 - Even though the code handles pages B0h and B2h, those pages aren't
   mentioned in the Supported VPD Pages list, so eg the Linux SCSI stack
   won't actually try to use them.

Fix these problems and make things more robust to avoid future problems
by moving to a table of supported VPD pages, which means that any added
VPD page support will automatically get reported on page 0.
