[PATCH v3] driver core: platform: set numa_node before platform_add_device()

[Jinhui Guo <guojinhui.liam@bytedance.com>]

From: "Jinhui Guo" <guojinhui.liam@bytedance.com>

platform_add_device creates numa_node attribute of sysfs according to
whether dev_to_node(dev) is equal to NUMA_NO_NODE. So set the numa node
of the device before creating numa_node attribute of sysfs.

Fixes: 4a60406d3592 ("driver core: platform: expose numa_node to users in sysfs")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202309122309.mbxAnAIe-lkp@intel.com/
