[PATCH] b43 drivers: remove IEEE80211_CONF_SSID_HIDDEN

[Johannes Berg <johannes@sipsolutions.net>]

The IEEE80211_CONF_SSID_HIDDEN setting is unclear but does not
match the "closed net" flag b43 hardware has; the flag influences
only the sending of probe responses which is disabled anyway.
>From looking at the microcode, I can see that if the flag is set
then probe requests are required to be directed to the BSSID of
the AP to be answered by the microcode, but this not interesting
because we don't support probe request offload anyway.

This patch removes the IEEE80211_CONF_SSID_HIDDEN use from
both b43 drivers.

I've also clarified the specs, please queue the change to your
respective drivers.
