After the virNetDaemonAddServerPostExec call in virtlogd we should have
netserver refcount set to 2. One goes to netdaemon servers hashtable
and one goes to virt{logd,lock} own reference to netserver. Let's add
the missing increment in virNetDaemonAddServerPostExec itself while
holding the daemon lock.
Since lockd defers management of the @srv object by the presence
in the hash table, virLockDaemonNewPostExecRestart must Unref the
alloc'd Ref on the @srv object done as part of virNetDaemonAddServerPostExec
and virNetServerNewPostExecRestart processing. The virNetDaemonGetServer
in lock_daemon main will also take a reference which is Unref'd during
main cleanup.
