[PATCH] NetConfigDevice: ignore address deletion fail

[Ondrej Lichtner]

From: Ondrej Lichtner <olichtne(a)redhat.com&gt;

The slave would crash on trying to remove an ip address that doesn't
exist on the device. This can happen for a variety of reasons, for
example the user removes the address in one of the tasks. This patch
fixes the crash.
