From: Johannes Berg <johannes.b...@intel.com>
There's no need for the second conditional as the same will be
done immediately afterwards if there's no station assigned.
Remove the useless conditional, move fallback assignment into
the else branch and don't try to look up a multicast address
which cannot be found anyway.
