[PATCH 2/7] unevictable lru: defer vm event counting

[Lee Schermerhorn <lee.schermerhorn@hp.com>]

Fix to unevictable-lru-infrastructure.patch

NORECL_* events are not defined this early in the series.
Remove the event counting from this patch and add in with
unevictable lru statistics [subsequent patch].
