virtio-rng: Keep the default backend out of VirtIORNGConf

Browse source 
The default backend is only used within virtio_rng_device_realize().
Replace VirtIORNGConf member default_backend by a local variable.
Adjust its type to reduce conversions.

While there, pass &error_abort instead of NULL when failure would be a
programming error.
