essid_len in SIOCSIWESSID

[Pedro Ramalhais]

Hi Jouni and Jean!
I've noticed that wpa_suplpicant is causing the essid to be set
incorrectly. wpa_supplicant is setting

iwr.u.essid.length = ssid_len

but wireless tools is setting

wrq.u.essid.length = strlen(essid) + 1

in SIOCSIWESSID.

So, which one is correct?
Thanks!
