[PATCH 2/2] arm64/numa: fix incorrect print of end_pfn

[Hanjun Guo]

From: Hanjun Guo <hanjun.guo at linaro.org>

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 should be 0, not 0xffffffffffffffff as there is
no memory on that node.

Fixes: 1a2db300348b ("arm64, numa: Add NUMA support for arm64 platforms.")
