Nico Huber 744d6bd638 sb/intel: Check for NULL-return of pcidev_on_root() 
In these cases we have to expect a NULL pointer because the IGD
device 0:2.0 may be disabled.

The behaviour still differs from using dev_find_slot(), which may
return a disabled device. Though, if you'd try to read its config
space you'd only read garbage (0xff) and in cases where we filled
ACPI data with devicetree information, the information shouldn't
be interpreted by the OS because of the disabled device.
