acpi, nfit, libnvdimm: fix interleave set cookie calculation (64-bit comparison)
While reviewing the -stable patch for commit 86ef58a4 "nfit, libnvdimm: fix interleave set cookie calculation" Ben noted: "This is returning an int, thus it's effectively doing a 32-bit comparison and not the 64-bit comparison you say is needed." Update the compare operation to be immune to this integer demotion problem.
