PCI: Prevent out of bounds access in numa_node override

d4aa930aed2d ("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: d4aa930aed2d ("PCI: Allow numa_node override via sysfs")
