virtio_pci_modern: __force cast the notify mapping
When switching virtio_pci_modern to use a helper for mappings we lost an
__iomem tag. We should restore it.
However, virtio_pci_modern is playing tricks by hiding an iomem pointer
in a regular vq->priv pointer. Which is okay as long as it's
all contained within a single file, but we need to __force cast
the value otherwise we'll get sparse warnings.
