virtio-net: set queues after driver_ok
Commit 25266128fe16 ("virtio-net: fix race between set queues and
probe") tries to fix the race between set queues and probe by calling
_virtnet_set_queues() before DRIVER_OK is set. This violates virtio
spec. Fixing this by setting queues after virtio_device_ready().
Note that rtnl needs to be held for userspace requests to change the
number of queues. So we are serialized in this way.
