x86/PCI: Check pcie_find_root_port() return for NULL
If pcie_find_root_port() is unable to locate a Root Port, it will return
NULL. Check the pointer for NULL before dereferencing it.
This particular case is in a quirk for devices that are always below a Root
Port, so this won't avoid a problem and doesn't need to be backported, but
check as a matter of style and to prevent copy/paste mistakes.
