    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
