Pull libnvdimm fixes from Dan Williams:
 "I debated holding this back for the v5.2 merge window due to the size
  of the "zero-key" changes, but affected users would benefit from
  having the fixes sooner. It did not make sense to change the zero-key
  semantic in isolation for the "secure-erase" command, but instead
  include it for all security commands.

  The short background on the need for these changes is that some NVDIMM
  platforms enable security with a default zero-key rather than let the
  OS specify the initial key. This makes the security enabling that
  landed in v5.0 unusable for some users.

  Summary:

   - Compatibility fix for nvdimm-security implementations with a
     default zero-key.

   - Miscellaneous small fixes for out-of-bound accesses, cleanup after
     initialization failures, and missing debug messages"
