Pull virtio updates from Michael Tsirkin:
 "A small number of improvements all over the place:

   - vdpa/octeon support for multiple interrupts

   - virtio-pci support for error recovery

   - vp_vdpa support for notification with data

   - vhost/net fix to set num_buffers for spec compliance

   - virtio-mem now works with kdump on s390

  And small cleanups all over the place"
