Subject: thp: account anon transparent huge pages into NR_ANON_PAGES

We use NR_ANON_PAGES as base for reporting AnonPages to user.  There's
not much sense in not accounting transparent huge pages there, but add
them on printing to user.

Let's account transparent huge pages in NR_ANON_PAGES in the first place.
