Replace use of the legacy vm_flags_t flags with vma_flags_t values where
VMA flags are tested directly in /proc/$pid/[s]maps, pagemap, clear_refs
and PROCMAP_QUERY.
In replacing vm_flags_clear() (which takes the VMA write lock) with
vma_clear_flags() (which does not) in clear_refs_write(), we explicitly
write lock the VMA. The mmap write lock is already held at this point.
The show_vma_header_prefix() and show_smap_vma_flags() output functions and
the thp_vma_allowable_orders() call continue to use legacy flags for the
time being.
No functional change intended.
