libertas: detect TX lockups and reset hardware
Recent patches added support for resetting the SD8686 hardware when

iwlagn: iwl-agn-rs: remove unnecessary null check for sta and lq_sta
both sta and lq_sta are guaranteed to be not null in the
calling function so we don't need to check them here.

cfg80211/mac80211: apply station uAPSD parameters selectively
Currently, when hostapd sets the station as authorized
we also overwrite its uAPSD parameter. This obviously
leads to buggy behaviour (later, with my patches that
actually add uAPSD support). To fix this, only apply
those parameters if they were actually set in nl80211,
and to achieve that add a bitmap of things to apply.
