[libvirt] [PATCH] network: Don't remove transient network if creating of config file fails

[Peter Krempa]

On the off-chance that creation of persistent configuration file would
fail when defining a network that is already started as transient, the
code would remove the transient data structure and thus the network.

This patch changes the code so that in such case, the network is again
marked as transient and left behind.
