node_device_udev: Fix leak of mdevctlLock, udevThreadCond, and mdevCtlMonitors

Browse Source 
Even if `priv->udev_monitor` was never initialized, the mdevctlLock, udevThread
were. Therefore let's match the order of releasing the resources the order of
allocating the resources in `nodeStateInitialize`.

In addition, use `g_steal_pointer` in `g_list_free_full`.
