Subject: [PATCH 2/2] sg_inq: Do not export long identifiers

Some targets (accidentally) display really long vendor specific
IDs. These will cause a pathname overflow when udev tries to
generate links based on that name.
So skip any vendor-specific IDs which are longer than 128 characters;
vendor-specific IDs are of limited usage anyway.
