PCI: of_property: Handle interrupt parsing failures
of_pci_prop_intr_map() uses uninitialized addr_sz[] values if
of_irq_parse_raw() fails, which leads to intermittent crashes.
Clear addr_sz[] before use so we never use uninitialized elements.
If no valid IRQs are parsed, don't bother adding the interrupt-map
property.
Fixes: 407d1a51921e ("PCI: Create device tree node for bridge")
