Subject: [PATCH 58/99] selinux: Disconnect before closing the handle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

libsemanage documentation says:
~~~~
be sure that a semanage_disconnect() was previously called if the handle
was connected.
~~~~

Otherwise we get a memory leak.
