Prevent IDE boot ops on NUMA system
Without this patch a Opteron test system here oopses at boot with
current git.
Calling to_pci_dev() on a NULL pointer gives a negative value so the
following NULL pointer check never triggers and then an illegal address
is referenced. Check the unadjusted original device pointer for NULL
instead.
