5.4-stable review patch. If anyone has any objections, please let me know.

From: Haibo Xu haibo1.xu@intel.com
commit a21dcf0ea8566ebbe011c79d6ed08cdfea771de3 upstream.
Currently, only acpi_early_node_map[0] was initialized to NUMA_NO_NODE. To ensure all the values were properly initialized, switch to initialize all of them to NUMA_NO_NODE.
