[PATCH] net/virtio: unregister virtio user memery event to fix memory leak problem

[Harold Huang]

When eth_virtio_dev_init is failed, the registered virtio user memery is
not released and creating a new virtio user dev could be failed becase the
new dev could use the same address pointer and the register virtio user
memory to the same address is not allowed.
