PCIe switch can be connected directly to the PCIe root complex in QEMU;
ASPM does not expect this topology and dereferences NULL pointer when
initializing.
Downstream port can be also connected to the root complex without
upstream one, so code checks for both, otherwise they dereference NULL

PCIe switch upstream port can be connected directly to the PCIe root bus
in QEMU; ASPM does not expect this topology and dereferences NULL pointer
when initializing.
I have not confirmed this can happen on real hardware, but it is presented
as a feature in QEMU, so there is no reason to panic if w
