dm: pci: Fix device PCI iteration
When there is no PCI bus uclass_first_device will return no bus and no
error which will result in pci_find_first_device calling
skip_to_next_device with no bus, and the bus is only checked at the end
of the while cycle, not the beginning.
Fixes: 76c3fbcd3d ("dm: pci: Add a way to iterate through all PCI devices")
