    i2c: virtio: mark device ready before registering the adapter

    virtio_i2c_probe() synchronously probes child i2c drivers on the bus,
    but peripherals may use the bus at probe for tasks like reading a chip
    id. The vhost-user-i2c backend stalls at such probes unless DRIVER_OK
    is already set before the virtqueue is first kicked.

    Set DRIVER_OK explicitly before i2c_add_adapter(), as done for the
    same reason in commit f5866db64f34 ("virtio_console: enable VQs
    early") and commit 71e4b8bf0482 ("virtio_rpmsg: set DRIVER_OK before
    using device").
