[Libvir] PATCH: Fix uninitialized variable & bridge setup

[Daniel P. Berrange]

Two crazy bugs

 - I forgot an =0 initialization in a recent patch to deal with qemu startup
 - If you don't have any virtual networks defined, then libvirt_qemud will
   never called  brctlInit()  so trying to start a guest using bridged 
   network will get EINVAL.
