Alexander Wetzel fd081afd21 wifi: cfg80211: Fix use after free for wext 
commit 015b8cc5e7 upstream.

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: fffd0934b9 ("cfg80211: rework key operation")
