mac80211: allow the driver not to pass the tid to ieee80211_sta_uapsd_trigger

Browse Source 
iwlwifi will check internally that the tid maps to an AC
that is trigger enabled, but can't know what tid exactly.
Allow the driver to pass a generic tid and make mac80211
assume that a trigger frame was received.
