[PATCH] drivers/net/wireless: correct reported ssid lengths
ESSIDs can technically include NULL characters. Drivers should not be
adjusting the length of the ESSID before reporting it in their
SIOCGIWESSID handlers. Breaks stuff like wpa_supplicant. Note that ipw
drivers, which seem to currently be the "most correct", don't have this
problem.
