s390/virtio: remove unused header file kvm_virtio.h

Browse source 
With commit 7fb2b2d512 ("s390/virtio: remove the old KVM virtio
transport") the pre-ccw virtio transport for s390 was removed. To
complete the removal the uapi header file that contains the related data
structures must also be removed.
