OvmfPkg: Rerun dispatcher after initializing virtio-rng
Since the pixiefail CVE fix the network stack requires a hardware random number generator. This can currently be a modern CPU supporting the RDRAND instruction or a virtio-rng device. The latter is initialized during the BDS phase. To ensure all depending (network) modules are also started, we need to run the dispatcher once more after the device was initialized. Without this, network boot is not available under certain hardware configurations.
