[SPARC64]: Fix pci_intmap_match().
When crawling up the PCI bus chain, stop at the first node that has an interrupt-map property before we hit the root. Also, if we use a bus interrupt-{map,mask} do not forget to update the 'intmask' pointer as we do for the 'intmap' pointer. Signed-off-by: David S. Miller <davem@davemloft.net>
