PageTransCompoundMap() returns true for hugetlbfs and THP

treated as THP faults.
Tighten the check to filter out hugetlbfs pages. This also leads to
consistently mapping all unsupported hugepage sizes as PTE level
entries at stage 2.

FWIW, I've cherry-picked that single patch from the series and queued it
for 4.20.
Thanks,
