[PATCH 3/3 master] Fix traceback after Delete in nm-c-e (#642370)

[Radek Vykydal <rvykydal redhat com>]

The traceback occurs if network enablement is not successful
after deleting a connection in nm-c-e. The reason is that
nm-c-e deletes corresponding ifcfg file. The fix is to update
network object in each iteration of network enablement loop.
