Subject: network: Resolve Coverity FORWARD_NULL
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=ec010a55e7de72f493b1c53b2cb10c6bc433fd58;p=libvirt.git

network: Resolve Coverity FORWARD_NULL

Commit id 'ca481a6f' added virNetworkRouteDefFree which may be called
in an error path from lxcAddNetworkRouteDefinition with 'route = NULL'.
So just add the (!def) at the top to resolve.
