The define for_each_pci_dev(d) is:
while ((d = pci_get_device(PCI_ANY_ID, PCI_ANY_ID, d)) != NULL)
Thus, the list iterator 'd' is always non-NULL so it doesn't need to
be checked. So just remove the unnecessary NULL check. Also remove the
unnecessary initializer because the list iterator is always initialized.
