Bug description:
  [Impact]

   * Users can not rename their disks properly.

   * HP BIOS looks for a partition named HP_TOOLS for their recovery
  key.

   * Because we don't have an mlabel that works, the recovery key does
  not work on HP laptops. Thus, it is impossible for an end user to
  recover their system if they somehow manage to break the main install.

  [Test Case]

   * Use mlabel to label a partition

   * Observe the name is not exactly as intended

  [Regression Potential]

   * Low, this fix has already been upstream for a few releases.

   * Additionally, at 20 additional lines of code, it isn't that large
  of a change.

  [Original Description]

  I try to rename a usb stick using mlabel (gparted shows the same
  erroneous behaviour). The rename works, but the string "nA" is
  appended to the name (it is less than 11 characters). The appended
  string is right-justified, and spaces are inserted in the middle
  between my name and the "nA", resulting in a new label like "new-name
  nA". This behaviour only takes place with names that are at least 8
  characters long.
