4.14-stable review patch. If anyone has any objections, please let me know.

[ 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.
