[libvirt] [PATCH] virNetServerNewPostExecRestart: Initialize @max_anonymous_clients
Coverity spotted a use of possibly undefined variable. If a server is
restarting as an result of update, the JSON file that keeps current
value of some variables will not contain the new variables. This is
the case of @max_anonymous_clients too. We are correctly querying if
there's "max_anonymous_clients" in the JSON, however, we are not
setting a sane default if there's none.
