Fix the PRT entry code in acpi_pci_link to always add the entry, even if

there is no irq link.  Since we now use the stored copy of PRT, not the
one that used to be passed into acpi_pcib_route_interrupt(), we need it in
the list. [1]

Fix a bug in acpi_pci_find_prt() where we weren't checking the bus, thus
choosing the wrong PRT entry to use for routing the link.  Also, add a
printf for the case where the PRT entry is not found as this should not
happen.
