PCI: Prevent out of bounds access in numa_node override
63692df103e9 ("PCI: Allow numa_node override via sysfs") didn't check that
the numa node provided by userspace is valid. Passing a node number too
high would attempt to access invalid memory and trigger a kernel panic.
Fixes: 63692df103e9 ("PCI: Allow numa_node override via sysfs")
