This fixes the output of sg_vpd trying to fetch VPD pages and reporting failure:

Applied upstream. Will appear when the next subversion revision is pushed to this github mirror.
Thanks.
BTW Starting to add JSON support. Starting small, so far with sg_opcodes and sg_rep_zones. Try the --json[=JO] option.
