Starting with v4.8, we allow a PCIe port to runtime suspend to D3hot if the port itself and its children satisfy a number of conditions. Once a child is removed, we recheck those conditions in case the removed device was blocking the port from suspending. The rechecking needs to happen *after* the device has been removed from the bus it resides on. Otherwise when walking the port's subordinate bus in pci_bridge_d3_update(), the device being removed would erroneously still be taken into account. However the device is removed from the bus_list in pci_destroy_dev() and we currently recheck *before* that. Fix it.
