mm/memory_hotplug: fix section mismatch
With CONFIG_MEMORY_HOTPLUG I got following warning: WARNING: vmlinux.o(.text+0x1276b0): Section mismatch in reference from the function hotadd_new_pgdat() to the function .meminit.text:free_area_init_node() The function hotadd_new_pgdat() references the function __meminit free_area_init_node(). This is often because hotadd_new_pgdat lacks a __meminit annotation or the annotation of free_area_init_node is wrong. Use __ref to fix this.
