mm/mm_init: remove unnecessary initialization of pgdat->per_cpu_nodestats

Browse Source 
free_area_init_node() sets pgdat->per_cpu_nodestats to NULL and later
calls free_area_init_core(), which unconditionally overwrites it with
&boot_nodestats. Nothing reads the field in between, so the store has
no effect.

Remove unnecessary initialization. No functional change.
