Fixed a kernel oops on module unload by adding spin lock protection to
ieee80211's crypt handlers (thanks to Zhu Yi)

Modified scan result logic to report WPA and RSN IEs if set (vs.being
based on wpa_enabled)

Added ieee80211_device as the first parameter to the crypt init()
method.  TKIP modified to use that structure for determining whether to
countermeasures are active.
