ath9k: /proc/net/wireless always shows status of 0

[Ben Greear <greearb@candelatech.com>]

This is with today's wireless-testing (with no extra hacks)

[root@a230-ath9k ~]# cat /proc/net/wireless
Inter-| sta-|   Quality        |   Discarded packets               | Missed | WE
  face | tus | link level noise |  nwid  crypt   frag  retry   misc | beacon | 22

The interface is running WPA and is passing traffic, so I'd expect some sort of
useful status.  Is this a known issue?

[root@a230-ath9k ~]# iwconfig wlan0

Thanks,
