Libertas: fix WARN_ON issues in cfg80211 support
In following scenarios WARN_ON() in cfg80211 code was triggered. a) Driver unload or card removal. b) Disconnect from infra network c) Adhoc start/join d) Adhoc stop Added following fixes to avoid WARN_ON() in cfg80211 code. a) Ensured that cfg80211_disconnected() function defined in cfg80211 code will be called only in infra mode. b) Solved timing issue by moving cfg80211_disconnected() call inside lbs_cfg_disconnect(). c) Updated "wdev->ssid" in driver code after Adhoc join/start d) Removed unnecessory cfg80211_disconnected() call in lbs_remove_card.
