Pull VFIO fixes from Alex Williamson:

 - Honor reserved regions when testing for IOMMU find grained super page
   support, avoiding a regression on s390 for a firmware device where
   the existence of the mapping, even if unused can trigger an error
   state. (Niklas Schnelle)

 - Fix a deadlock in releasing KVM references by using the alternate
   .release() rather than .destroy() callback for the kvm-vfio device.
