vfio: Change vfio_external_check_extension() to vfio_file_enforced_coherent()
Instead of a general extension check change the function into a limited
test if the iommu_domain has enforced coherency, which is the only thing
kvm needs to query.
Make the new op self contained by properly refcounting the container
before touching it.
