bc5627d91f Fix handling of data frames queued for a station in power save mode: 
don't mark the MORE_DATA bit when taking it off the ps queue, there's
no 802.11 header then; we must wait to do this at encap time so
mark the mbuf instead.

ebdda46c84 Fix race condition in handling node reference counts for authenticating 
stations in ap mode.  Track when a node's first auth frame is
received and use this to decide whether or not to bump the refcnt.
This insures we only ever bump the refcnt once.

720bd46e9f Only update the scan entry state based on newly received frames. 
This fixes duplicative BSS entries(memory leaks as well) listed in
"ifconfig dev list scan" when a station fails to associate with an AP.
