[PATCH] softmac: Fix inability to associate with WEP networks

Commit 4cf92a3c was submitted as a fix for bug #8686 at bugzilla.kernel.org
(http://bugzilla.kernel.org/show_bug.cgi?id=8686). Unfortunately, the fix led to
a new bug, reported by Yoshifuji Hideaki, that prevented association for WEP
encrypted networks that use ifconfig to control the device. This patch effectively
reverts the earlier commit and does a proper fix for bug #8686.
