Fix exiting of libvirt_lxc program on container quit

Browse Source 
The virLXCControllerClientCloseHook method was mistakenly
assuming that the private data associated with the network
client was the virLXCControllerPtr. In fact it was just a
dummy int, so we were derefencing a bogus struct. The
frequent result of this was that we would never quit, because
we tried to arm a non-existant timer.

Fix the code by removing the dummy private data and just
using the virLXCControllerPtr instance as private data
