[GIT PULL] libnvdimm fix for 4.13-final

["Williams, Dan J" <dan.j.williams@intel.com>]

Hi Linus, please pull from:

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

...to receive a single patch removing some structure definitions from a
uapi header file. These payloads are never processed directly by the
kernel they are simply passed through an ioctl as opaque blobs to the
ACPI _DSM (Device Specific Method) interface.

Userspace should not be depending on the kernel to define these
payloads. We will instead provide these definitions via the existing
libndctl (https://github.com/pmem/ndctl) project that has NVDIMM
command helpers and other definitions.

    libnvdimm: clean up command definitions
    
    Remove the command payloads that do not have an associated libnvdimm
    ioctl. I.e. remove the payloads that would only ever be carried in the
    ND_CMD_CALL envelope. This prevents userspace from growing unnecessary
    dependencies on this kernel header when userspace already has everything
    it needs to craft and send these commands.
