acpi, nfit, libnvdimm: fix interleave set cookie calculation (64-bit comparison)
commit b03b99a329a14b7302f37c3ea6da3848db41c8c5 upstream.
While reviewing the -stable patch for commit 86ef58a4e35e "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.
