s390/pci: improve pci hotplug
PCI hotplug events basically notify about the new state of a
function. Unfortunately some hypervisors implement hotplug
events in a way where it is not clear what the new state of
the function should be.
Use clp_get_state to find the current state of the function
and handle accordingly.
