mm: rmap: abstract updating per-node and per-memcg stats
A lot of intricacies go into updating the stats when adding or removing
mappings: which stat index to use and which function. Abstract this away
into a new static helper in rmap.c, __folio_mod_stat().
This adds an unnecessary call to folio_test_anon() in
__folio_add_anon_rmap() and __folio_add_file_rmap(). However, the folio
struct should already be in the cache at this point, so it shouldn't cause
any noticeable overhead.
No functional change intended.
