Subject: [PATCH] wifi: cfg80211: sme: store capped length in
 __cfg80211_connect_result()

The QGenie AI code review tool says we should store the capped length to
wdev->u.client.ssid_len.  The AI is correct.

Fixes: 62b635dcd69c ("wifi: cfg80211: sme: cap SSID length in __cfg80211_connect_result()")
