[libvirt] [PATCH 4/5] Fix incorrect variable passed to LXC event callback

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

The wrong variable was being passed in with the LXC event callback
resulting in a later deadlock or crash

* src/lxc/lxc_driver.c: Pass 'vm' instead of 'driver' to event
  callback
