arm64/numa: fix incorrect log for memory-less node

Browse source 
When booting on NUMA system with memory-less node (no
memory dimm on this memory controller), the print
for setup_node_data() is incorrect:

NUMA: Initmem setup node 2 [mem 0x00000000-0xffffffffffffffff]

It can be fixed by printing [mem 0x00000000-0x00000000] when
end_pfn is 0, but print <memory-less node> will be more useful.

Fixes: 1a2db30034 ("arm64, numa: Add NUMA support for arm64 platforms.")
