Subject: [PATCH] LoongArch: Fix early_numa_add_cpu() usage for FDT systems

early_numa_add_cpu() applies on physical CPU id rather than logical CPU
id, so use cpuid instead of cpu.

Cc: stable@...r.kernel.org
Fixes: 3de9c42d02a79a5 ("LoongArch: Add all CPUs enabled by fdt to NUMA node 0")
Reported-by: Bibo Mao <maobibo@...ngson.cn>
