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.
