Dev Jain e3d8707358 selftests/mm/hmm-tests: test pagemap reads of PMD device-private entries 
To cover pagemap paths scanning PMD entries, add assertions to check
whether a device-private PMD entry has the correct pagemap information -
the PM_SWAP bit must be on in the pagemap entry.  Before that, we must
assert through HMM_DMIRROR_SNAPSHOT snapshot that the leaf entry is at PMD
level and not PTE level.
