virtio: Make disable-legacy/disable-modern compat properties optional
The disable-legacy and disable-modern properties apply only to some virtio-pci devices. Make those properties optional. This fixes the crash introduced by commit f6e501a28ef9 ("virtio: Provide version-specific variants of virtio PCI devices"): $ qemu-system-x86_64 -machine pc-i440fx-2.6 \ -device virtio-net-pci-non-transitional Unexpected error in object_property_find() at qom/object.c:1092: qemu-system-x86_64: -device virtio-net-pci-non-transitional: can't apply \ global virtio-pci.disable-modern=on: Property '.disable-modern' not found Aborted (core dumped) Reported-by: Thomas Huth <thuth@redhat.com> Fixes: f6e501a28ef9 ("virtio: Provide version-specific variants of virtio PCI devices") Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Cornelia Huck <cohuck@redhat.com> Reviewed-by: Michael S.
