[PATCH net 3/7] virtio_net: Fix not restoring real_num_rx_queues

[Toshiaki Makita]

When _virtnet_set_queues() failed we did not restore real_num_rx_queues.
Fix this by placing the change of real_num_rx_queues after
_virtnet_set_queues().
This order is also in line with virtnet_set_channels().

Fixes: 4941d472bf95 ("virtio-net: do not reset during XDP set")
