[PATCH] bcm43xx: Fix 802.11b/g scan limits to match regulatory reqs

In 802.11b/g mode, bcm43xx actively scans channels 1-14 no matter what
locale has been set, either in the sprom or by the locale option. This
behaviorviolates regulatory rules everywhere in the world except
Japan. This patch changes the default range to the correct value if the
locale has been set, and to channels 1-13 if no locale has been set.
