virtio: rng: disallow multiple device registrations, fixes crashes
commit e84e7a56a3aa2963db506299e29a5f3f09377f9b upstream.
The code currently only supports one virtio-rng device at a time.
Invoking guests with multiple devices causes the guest to blow up.
Check if we've already registered and initialised the driver. Also
cleanup in case of registration errors or hot-unplug so that a new
device can be used.
