Replace use of the legacy vm_flags_t flags with vma_flags_t values where
VMA flags are tested directly in the THP and khugepaged logic.

The thp_vma_allowable_orders() family of functions, hugepage_madvise() and
khugepaged_enter_vma() continue to take legacy flags for the time being.

Also update BUG_ON()'s to VM_WARN_ON_ONCE() while here.

No functional change intended.
