Log:
  Add FCCT M500 to the NCQ black list. Linux added it in 4.2 (August
  2015). Correct the M500 firmware versions. EU07 was the engineering
  test version, not the release version with the fix. MU07 is the
  release version. It's the only Micron firmware version to actually
  work. Remove support for EU07.
  
  This brings the blacklist into parity with the Linux blacklist as of
  4.5, except for the Micron M500 MU07 entry. I personally tested the
  MU07 firmware on 12 machines running 6 drives each with no corruption
  in the past 6 months with Netflix production loads. Prior versions of
  the M500 firmware wouldn't last more than a few days.
