[libvirt] [PATCH] Don't overwrite useful message when creating macvlan fails

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

Currently we report a bogus error message when macvlan
creation fails:

error: Failed to start domain migtest
error: operation failed: Unable to create macvlan device

With this removed, we see the real error:

error: Failed to start domain migtest
error: Unable to get index for interface p31p1: No such device
