Thomas previously requested a more meaningful message when plug of a
passthrough ISM device fails (interpretation facility required).  In
the process of creating that patch, I noticed that devices that fail 
s390_pcihost_plug during a hotplug scneario can potentially crash QEMU
because remnants of the associated S390PCIBusDevice were not properly
cleaned up.  So let's fix that too.

Matthew Rosato (2):
  s390x/pci: fix cleanup of failed hotplug
  s390x/pci: add message for ISM without zPCI interpretation
