[SCSI] Fix VPD inquiry page wrapper
Fix two bugs in the VPD page wrapper: - Don't return failure if the user asked for page 0 - The end of buffer check failed to account for the page header size and consequently didn't work Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Cc: Stable Tree <stable@kernel.org> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
