mm/page_ext: remove pgdat_page_ext_init()
pgdat_page_ext_init() sets pgdat->node_page_ext to NULL only on FLATMEM.
FLATMEM depends on !NUMA, so the pgdat is always the zero-initialized
contig_page_data and the store has no effect.
So remove the call site, the unused function and its declaration.
No functional change.
