[Qemu-devel] [PULL 2/2] hw/machine: Remove the Zero check of nb_numa_nodes for numa_complete_configuration()

[Eduardo Habkost <ehabkost@redhat.com>]

From: Dou Liyang <douly.fnst@cn.fujitsu.com>

Commit 7a3099fc9c5c("numa: postpone options post-processing till machine_run_board_init()")
broke the commit 7b8be49d36fc("NUMA: Enable adding NUMA node implicitly").

The machine_run_board_init() doesn't do NUMA setup if nb_numa_nodes=0,
but the numa_complete_configuration need add a new node if memory hotplug
is enabled (slots > 0) even nb_numa_nodes=0.

So, Remove the check for numa_complete_configuration() to fix this.

Fixes 7a3099fc9c5c("numa: postpone options post-processing till machine_run_board_init()")
