virtio-pci: fix level interrupts
mask notifiers are never called without msix, so devices with backend masking like vhost don't work. Call mask notifiers explicitly at startup/cleanup to make it work. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Tested-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
