It does fix this specific problem, but introduces a new one:

# echo online_movable > /sys/devices/system/memory/memory16/state
# cat /sys/devices/system/memory/memory16/valid_zones
Movable
# echo offline > /sys/devices/system/memory/memory16/state
# cat /sys/devices/system/memory/memory16/valid_zones
          <--- no output

Memory block 16 is the only one I onlined and offlineto ZONE_MOVABLE.
