Backport to stable nm-0-9-10: bridge availability

[poma <pomidorabelisima gmail com>]

Backport to stable nm-0-9-10,
bridge device availability due to disabling 'networking' prior to reboot.
See:
https://mail.gnome.org/archives/networkmanager-list/2015-April/msg00013.html
http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=568a8d1

Nevertheless "systemctl restart NetworkManager.service" is necessary.
