[libvirt] [PATCH] admin: Resolve leaked reference to private data

[Erik Skultety]

Running valgrind on a very simplistic program consisting only from
opening and closing admin connection (virAdmConnect{Open,Close}) shows a
leak in remoteAdminPrivNew, because the last reference to privateData is
not decremented, thus the object won't be disposed. This patch unrefs
the privateData object once we closed the active connection to daemon,
making further use of this connection  useless.
