Pull libnvdimm fixes from Dan Williams:
 "A crash fix, a build warning fix, a miscellaneous small cleanups.

  In case anyone is looking for them, there was a regression caught by
  testing that caused two patches to be dropped from this update.  Those
  patches have been reworked and will soak for another week / re-target
  5.0-rc4.

   - Fix driver initialization crash due to the inability to report an
     'error' state for a DIMM's security capability.

   - Build warning fix for little-endian ARM64 builds

   - Fix a potential race between the EDAC driver's usage of the NFIT
     SMBIOS id for a DIMM and the driver shutdown path.

   - A small collection of one-line benign cleanups for duplicate
     variable assignments, a duplicate header include and a mis-typed
     function argument"
