mm/memory_hotplug.c: fix the wrong usage of N_HIGH_MEMORY
In node_states_check_changes_online(), N_HIGH_MEMORY is used to substitute
ZONE_HIGHMEM directly. This is not right. N_HIGH_MEMORY is to mark the
memory state of node. Here zone index is checked, which should be
compared with 'ZONE_HIGHMEM' accordingly.
Replace it with ZONE_HIGHMEM.
This is a code cleanup - no known runtime effects.
