unreachable code in airo_set_auth()

[Dan Carpenter <error27@gmail.com>]

Smatch (http://repo.or.cz/w/smatch.git) complains about unreachable code 
in airo_set_auth() from drivers/net/wireless/airo.c

We don't actually commit the changes, but instead break on line 6577.  I 
didn't know what was intended there.  Or who the maintainer was.
