[Qemu-devel] [PATCH v4 18/29] Revert "vhost-net: do not crash if backend is not present" |

From: Marc-André Lureau <address@hidden>
Now that get_vhost_net() returns non-null after a successful
vhost_net_init(), we no longer need to check this case.
This reverts commit ecd34898596c60f79886061618dd7e01001113ad.
