mm/memory_hotplug: remove reset_node_managed_pages() in hotadd_init_pgdat()
managed pages has already been set to 0 in free_area_init_core_hotplug(),
via zone_init_internals() on each zone. It's pointless to reset again.
Furthermore, reset_node_managed_pages() no longer needs to be exposed
outside of mm/memblock.c. Remove declaration in include/linux/memblock.h
and define it as static.
In addtion to this, the only caller of reset_node_managed_pages() is
reset_all_zones_managed_pages(), which is annotated with __init, so it
should be safe to also mark reset_node_managed_pages() as __init.
