[PATCH 2/3] NetConfigCommon: return empty list from get_slave_options

[Ondrej Lichtner]

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

In case there are no slave options, the get_slave_options function
should return an empty list instead of None so that the function is
usable "for x in ..." loops.
