Use GetNetwork() only when having already aquired the lock, i.e. in CheckPrereq(). In LUNetworkConnect/Disconnect do not include Network info in Hooks environment, so that network locking can be avoided if conflicts are not checked. Invoke _CheckNodeGroupInstances() only in case of conflicts check, because otherwise owned instances are None, which results to an error.
