Currently zone_spanned_pages_in_node() and zone_absent_pages_in_node() are
non-static for ARCH_POPULATES_NODE_MAP and static otherwise.  However, only
the non-static versions are __meminit annotated, despite only being called
from __meminit functions in either case.

zone_init_free_lists() is currently non-static and not __meminit annotated
either, despite only being called once in the entire tree by
init_currently_empty_zone(), which too is __meminit.  So make it static and
properly annotated.
