PCI: Add pci_dev_show_local_cpu() to simplify code
local_cpus_show() and local_cpulist_show() are almost the same. This adds a new helper function, pci_dev_show_local_cpu(), to simplify code. The same strategy is already used by cpuaffinity_show() and cpulistaffinity_show(). Signed-off-by: Yijing Wang <wangyijing@huawei.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
