iwlwifi: introduce iwl_sta_id_or_broadcast
There are now five places where we need to
look up the station ID, but the sta pointer
may be NULL due to mac80211 passing that to
indicate a certain special state.
Replace all these by a new inline function,
called iwl_sta_id_or_broadcast(), and add
documentation about when to use it.
