Subject: [ 20/21] staging: wlan-ng: Fix clamping of returned SSID length

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tormod Volden <debian.tormod@...il.com>

commit 811a37effdb11e54e1ff1ddaa944286c88f58487 upstream.

Commit 2e254212 broke listing of available network names, since it
clamped the length of the returned SSID to WLAN_BSSID_LEN (6) instead of
WLAN_SSID_MAXLEN (32).
