virtio_pci_modern: correct sparse tags for notify
When switching virtio_pci_modern to use a helper for mappings we lost an __iomem tag. Restore it. Reported-by: kernel test robot <lkp@intel.com> Fixes: 9e3bb9b79a71 ("virtio_pci_modern: introduce helper to map vq notify area") Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
