[GIT PULL] libnvdimm fixes for 5.1-rc6

[Dan Williams]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-fixes-5.1-rc6

...to receive an optional libnvdimm update for v5.1-rc6. 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.
