[PATCH] PCI: Use insert_resource in pci_claim_resource

On ia64, the parent resources are not necessarily PCI resources and
so won't get found by pci_find_parent_resource.  Use the shiny new
insert_resource() function instead, which I think we would have used
here had it been available at the time.
