NetworkManager/src/devices/nm-device-ethernet.c
Beniamino Galvani daad4e2fee device: check ifindex before changing ethernet link settings 
During the call to deactivate(), the device can already have lost the
ifindex. Add a check for that to prevent assertion:

 ((src/platform/nm-platform.c:3306)): assertion 'g_return_val_if_fail(ifindex > 0, FALSE)' failed
