udev: distinguish host-managed zoned block in scsi_id

According to SPC4, the value of 0x14 is reserved to distinguish
host managed zoned block, e.g., some SMR (Shingled Magnetic Recording)
disks.

Other utilities such as sg3_utils can successfully recognize such
kind of disks. This patch implements the same ability.
