wifi: cfg80211: Fix use after free for wext
Key information in wext.connect is not reset on (re)connect and can hold
data from a previous connection.
Reset key data to avoid that drivers or mac80211 incorrectly detect a
WEP connection request and access the freed or already reused memory.
Additionally optimize cfg80211_sme_connect() and avoid an useless
schedule of conn_work.
Fixes: fffd0934b939 ("cfg80211: rework key operation")
