Subject: [PATCH] lxc: Don't crash if no security driver is specified in
 libvirt_lxc

https://bugzilla.redhat.com/show_bug.cgi?id=880064

When no security driver is specified libvirt_lxc segfaults as a debug
message tries to access security labels for the container that are not
present.

This problem was introduced in commit 6c3cf57d6cb27cf10064baf8cca0f39.
(cherry picked from commit 99a388e612d82a6bcd3462e4b98463fb32931520)
