[libvirt] [PATCH 1/4] security: Grab a reference to virSecurityManager for transactions

[Michal Privoznik]

This shouldn't be needed per-se. Security manager shouldn't
disappear during transactions - it's immutable. However, it
doesn't hurt to grab a reference either - transaction code uses
it after all.
