mm/memory_hotplug.c:1148:13: warning: ‘reset_node_present_pages’ defined but not used [-Wunused-function]
1148 | static void reset_node_present_pages(pg_data_t *pgdat)
| ^~~~~~~~~~~~~~~~~~~~~~~~
reset_node_present_pages() now only used in node_reset_state(),move it
inside the ifdef block to fix this warning.
