Aleksandr Mishin ebcb06e004 PCI: al: Check IORESOURCE_BUS existence during probe
[ Upstream commit a9927c2cac ]

If IORESOURCE_BUS is not provided in Device Tree it will be fabricated in
of_pci_parse_bus_range(), so NULL pointer dereference should not happen
here.

But that's hard to verify, so check for NULL anyway.
