mac80211_hwsim: fix check for custom world regdom array size
David Binderman reports that the conditions in the first loop
are the wrong way around - checking the array contents before
the size.
Instead of leaving the empty loop there and reordering the two
checks unify it into a single loop that skips over non-matches
and exits after the first match.
