Bug description:
  [Impact]

   * udf filesystems with blocksize < 2048 will not automount at startup.
   * udf filesystems with blocksize < 2048 will not show or be mounted by volume label (vid).

  [Test Case]

  Install udftools and create udf file system with volume id and
  blocksize < 2048:

  "sudo mkudffs -b 512 --vid=space /dev/sdb1"

  Run blkid on device: "sudo blkid /dev/sdb1"

  Without patch, output will be 'TYPE="udf"'. With patch, output will be
  'TYPE="udf" LABEL="space"'.

  Add /dev/sdb1 to /etc/fstab. Without patch, file system will fail to
  mount at boot; with patch, file system will mount at boot.

  Add LABEL=space to /etc/fstab. Without patch, file system will fail to
  mount; with patch, file system will mount.

  [Regression Potential]

  * This issue has been identified upstream and a patch is available
  (git commit 5a45eb2d2c70dc7ea2ff4c7b56ab8dba2780f033 in karelzak/util-
  linux).
