mm/page_alloc: Avoid ABI change in 4.9.65

Commit d135e5750205 "mm/page_alloc.c: broken deferred calculation"
renamed pglist_data::static_init_size to static_init_pgcnt.  However
the field has the same semantics as were intended originally (and in
any case, the field is only used by built-in code).  Hide the renaming
from genksyms.
