[ Upstream commit 3027a8e799b20fc922496a12f8ad2f9f36a8a696 ]

When a low level driver calls cfg80211_disconnected(), wep keys are
not cleared. As a result, following connection requests will fail
since cfg80211 internal state shows a connection is still in progress.

Fix this by clearing the wep keys when disconnecting.
